It seems the procedure for syncing this mirror with upstream is missing to push new tags. Cloning this repo today the latest four release tags v1.0.4[1-4] aren't there.

There is brk and exiting abnormal.

I've converted from make to CMake (it has better toolchain support - imho). I was trying to compile using clang, but there is at least one nested function in the Native pthread code, in particular allocatestack.c. It would be great to fix these as well, so that we can compile using other compilers.

E.g. mnt->mnt_opts = "rw,relatime,errors=remount-ro", hasmntopt(mnt, MNTOPT_RO) will match "errors".

As a practical matter, e2fsck with uClibc determines that a device mounted with read-write is read-only.

I'm not sure if this is a real problem or just my misunderstanding, but I noticed what I believe should be object files in the libc.a archive. They get compiled but do not appear to get into the archive. There are 45 of them. They are listed below. The configuration I used was with the default values, except for:

Target Architecture (TARGET_X86_64): 29
Enable shared libraries (HAVE_SHARED): n
Thread support: 3 (UCLIBC_HAS_THREADS_NATIVE)
Syslog support (UCLIBC_HAS_SYSLOG): n

Support fmemopen(), open_memstream(), and fopencookie() (glibc-compat) (UCLIBC_HAS_GLIBC_CUSTOM_STREAMS): y

I need to be able to test the build of uClibc, where only the static library libc.a is built (and not installed). Is there such a thing? Thanks.

I'm attempting to build uClibc from scratch using a combination of CMake and clang and/or gcc. I'd like to test my builds and have the uclibc-ng-test respository. I'd prefer not to actually install the libraries, but I want the build for the test code to use the code from the directory where I built it. I've tried using LD_LIBRARY_PATH, but want to see what would be the best way to do this and not use the libraries that are actually installed. Any direction someone can give me would be greatly appreciated.
