Hi,
I am trying to launch a Julia webserver but I ran into some difficulties. To be sure I've got the right tarball on your downloads page, I did:
root@bach:/tmp/julia# /lib/x86_64-linux-gnu/libc.so.6
GNU C Library (Ubuntu EGLIBC 2.13-20ubuntu5) stable release version 2.13, by Roland McGrath et al.

Then I downloaded and unpacked the tarball corresponding to libc 2.13.

Now, let me set the PATH as indicated in the instructions.
root@bach:/tmp# cd julia
root@bach:/tmp/julia# export PATH=$(pwd):$PATH
root@bach:/tmp/julia# echo $PATH
/tmp/julia:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin
I can now use the Julia prompt just fine. Now, onto the Julia webserver where I'm having problems. Here's my lighttpd.conf configuration:
root@bach:/tmp# cat /etc/lighttpd/lighttpd.conf
server.modules = (
"mod_access",
"mod_alias",
"mod_compress",
"mod_redirect",
"mod_scgi",
# "mod_rewrite",
)
server.document-root = "/tmp/julia/ui/website"
server.upload-dirs = ( "/var/cache/lighttpd/uploads" )
server.errorlog = "/var/log/lighttpd/error.log"
server.pid-file = "/var/run/lighttpd.pid"
server.username = "www-data"
server.groupname = "www-data"
server.port = 8002
index-file.names = ( "index.php", "index.html",
"index.htm", "default.htm",
" index.lighttpd.html" )
url.access-deny = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )
## Use ipv6 if available
#include_shell "/usr/share/lighttpd/use-ipv6.pl"
dir-listing.encoding = "utf-8"
server.dir-listing = "enable"
compress.cache-dir = "/var/cache/lighttpd/compress/"
compress.filetype = ( "application/x-javascript", "text/css", "text/html", "text/plain" )
include_shell "/usr/share/lighttpd/create-mime.assign.pl"
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"
scgi.server = (".scgi" => (("host" => "127.0.0.1", "port" => 8001)))
root@bach:/tmp#
Now, I will start the webserver.
root@bach:/tmp# /etc/init.d/lighttpd start
* Starting web server lighttpd [ OK ]
root@bach:/tmp#
root@bach:/tmp/julia# ./julia-release-webserver -p 8001
server started on port 8001.
0 open sessions.
1 open session [idle].
terminate called after throwing an instance of 'network::socket_error'
Aborted
Now I will do an strace on the same command:
root@bach:/tmp/julia# strace -o julia.txt -- ./julia-release-webserver -p 8001
server started on port 8001.
0 open sessions.
1 open session [idle].
terminate called after throwing an instance of 'network::socket_error'
Aborted
and its result is:
fstat(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f479a9f1000
write(1, "server started on port 8001.\n", 29) = 29
write(1, "0 open sessions.\n", 17) = 17
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3
setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(3, {sa_family=AF_INET, sin_port=htons(8001), sin_addr=inet_addr("0.0.0.0")}, 16) = 0
listen(3, 1) = 0
accept(3,
+++ killed by SIGABRT +++
I will also do an ltrace:
root@bach:/tmp/julia# ltrace -C -o juliaL.txt -- ./julia-release-webserver -p 8001
server started on port 8001.
0 open sessions.
1 open session [idle].
terminate called after throwing an instance of 'network::socket_error'
