preshing / cairo-windows Goto Github PK

I had a look into some github bots that can update dependencies to see if they can help here.
In the end dependencies.io looked like the best, as they can update system dependencies, not just python or ruby libraries.es.

There are two parts, a CLI tool, which doesn't require an API key, and a github workflow, which does.

These both read a yaml file that describes dependencies.

Getting an API key needs a license, which can be purchased, + there is a form which open source projects can apply for a free license from, I filled this in and @davegaeddert was super helpful.

Thanks so much for sharing this with the community ❤️

I am trying to follow the steps you laid out here and I also referenced the cairo end-to-end build win32 instructions. I installed Visual Studio Build Tools 2017, and then after that tried to install Visual Studio Community 2017 as well. I am getting the following error:

build-cairo-windows.sh: line 69: devenv.com: command not found
FAILED COMMAND: devenv.com "projects\vstudio\vstudio.sln" -upgrade

Is there something different I need to install to get devenv.com? Do I need to get an older version of Microsoft Visual C++ Studio Express? I tried looking it up, but I had a hard time finding good information. Thanks!

Hello! I've been attempting to build this for the past day, but ended up on a strange linking error that I couldn't overcome. The script finishes all the way past the cairo code files, but generates errors from "zlib/deflate.c" once it tries to make the final lib for cairo. Here's a screenshot of the x86 Command Prompt.

Thanks for your project that works fine, except for pdf. I tried with success png and svg backends (from Zetcode cairo graphics tutorial), but didn't manage to make pdf backend work, it only creates a blank file that has 0 pages. Is there something that need to be added to have pdf support ?

Hi @preshing
Any chance of doing a release with the current version of Cairo?

Is it worth seeing up some kind of a bot to alert when a new version of Cairo is out?

I tried building locally, but it seems to get stuck trying to load the solution from the projects folder.
Am I missing a step ?

Use:
devenv  [solutionfile | projectfile | folder | anyfile.ext]  [switches]

The first argument for devenv is usually a solution file, project file or a folder.
You can also use any other file as the first argument if you want to have the
file open automatically in an editor. When you enter a project file, the IDE
looks for an .sln file with the same base name as the project file in the
parent directory for the project file. If no such .sln file exists, then the
IDE looks for a single .sln file that references the project. If no such single
.sln file exists, then the IDE creates an unsaved solution with a default .sln
file name that has the same base name as the project file.

Command line builds:
devenv solutionfile.sln /build [ solutionconfig ] [ /project projectnameorfile [ /projectconfig name ] ]
Available command line switches:

/Build                  Builds the solution or project with the specified solution
                        configuration. For example "Debug". If multiple platforms
                        are possible, the configuration name must be enclosed in quotes
                        and contain platform name. For example: "Debug|Win32".
/Clean                  Deletes build outputs.
/Command                Starts the IDE and executes the command.
/Deploy                 Builds and then deploys the specified build configuration.
/DoNotLoadProjects      Opens the specified solution without loading any projects.
/Edit                   Opens the specified files in a running instance of this
                        application. If there are no running instances, it will
                        start a new instance with a simplified window layout.
/LCID                   Sets the default language in the IDE for the UI.
/Log                    Logs IDE activity to the specified file for troubleshooting.
/NoVSIP                 Disables the VSIP developer's license key for VSIP testing.
/Out                    Appends the build log to a specified file.
/Project                Specifies the project to build, clean, or deploy.
                        Must be used with /Build, /Rebuild, /Clean, or /Deploy.
/ProjectConfig          Overrides the project configuration specified in the solution
                        configuration. For example "Debug". If multiple platforms are
                        possible, the configuration name must be enclosed in quotes
                        and contain platform name. For example: "Debug|Win32".
                        Must be used with /Project.
/Rebuild                Cleans and then builds the solution or project with the
                        specified configuration.
/ResetSettings          Restores the IDE's default settings, optionally resets to
                        the specified VSSettings file.
/ResetSkipPkgs          Clears all SkipLoading tags added to VSPackages.
/Run                    Compiles and runs the specified solution.
/RunExit                Compiles and runs the specified solution then closes the IDE.
/SafeMode               Launches the IDE in safe mode loading minimal windows.
/Upgrade                Upgrades the project or the solution and all projects in it.
                        A backup of these files will be created as appropriate. Please
                        see Help on 'Visual Studio Conversion Wizard' for more
                        information on the backup process.

Product-specific switches:

/debugexe       Open the specified executable to be debugged. The remainder of
                the command line is passed to this executable as its arguments.
/diff           Compares two files.  Takes four parameters:
                SourceFile, TargetFile, SourceDisplayName(optional),
                TargetDisplayName(optional)
Join collaboration session
/TfsLink        Opens Team Explorer and launches a viewer for the
                provided artifact URI if one is registered.
/useenv         Use PATH, INCLUDE, LIBPATH, and LIB environment variables
                instead of IDE paths for VC++ builds.

To attach the debugger from the command line, use:
        VsJITDebugger.exe -p <pid>

Hello,

First of all thanks so much for this. I've followed the instructions and built the DLLs without any problems at all, used it in my app and it's really improved the graphics performance (it's a wxWidgets based application). Rendering on Windows was slow, now it's much faster.

wxWidgets is hard coded to try and load "libcairo-2.dll". I can change that easily with a patch on my build system. It seems though that the pre-built binaries mentioned on the cairo download page is named "libcairo-2.dll".

So would it be best to also output libcairo-2.dll from this script as well?

I'm only asking as I need to either modify wxWidgets to use cairo.dll and link with cairo.lib, or change your script to output libcairo-2.dll and libcairo-2.lib (I cannot just rename the lib as it will still expect to find cairo.dll).

Thanks again,

Tony.

Is there an easy way to see which features cairo-windows had enabled when Cairo was built?

Hello all,

First, thanks for this. I'm using it as a renderer in a wxWidgets application, it's much faster than the default, 2D and GDI+ renderers.

One of our users has reported a problem. They use Chinese characters 易感者, which just display as three square boxes when using Cairo. I've searched the web, and found an old post saying they had trouble with Chinese characters. But found another post saying Chinese characters were fine. Japanese characters also display as square boxes, so I'm guessing it's a unicode problem. They all display fine using the other renderers provided in wxWidgets.

Could this be an issue with Cairo or maybe the way it's built?

Thanks in advance,

Tony.

I see @stuaxo setting up a script to update dependencies. Also, I prefer setting up a CI(May be Github Actions) to build and release when anything is updated. This would help us maintain the version of Cairo to latest and can be automated.

I tried https://github.com/naveen521kk/cairo-windows/runs/1037141588. Maybe if @preshing help me we can complete this easily.

cairo upstream recently got support for the meson build system which also supports Windows builds with MSVC.

Since this project seems to be one of the last users of the make based win32 build system, porting would allow upstream cairo to drop this old build system code.

I tried to compile for x86 but zlib failed.
