Re: [Vala] Vala on CentOS?

Jürg,
Hmm... So I tried a lower glib target and its missing the checksum
which i guess is in the newer glib.
# valac --target-glib=2.12 --pkg=gee-1.0 --pkg=json-glib-1.0 main.vala
taxonomy.vala
./main: symbol lookup error: ./main: undefined symbol:
g_compute_checksum_for_string

Abderrahim,
I did try what you suggested. Which lets it compile without the weird
Xcc option. However running it still makes all share libraries go to
/lib64/xxxx:
# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
# pkg-config --modversion glib-2.0
2.22.5
# valac --target-glib=2.22 --pkg=gee-1.0 --pkg=json-glib-1.0 main.vala
taxonomy.vala
# ./main
./main: symbol lookup error: ./main: undefined symbol: g_once_init_enter_impl

I tried "ldd" on the "main" executable and everything keeps linking to
/lib64/ rather then /usr/local/lib:
# ldd main
        libgee.so.2 => /lib64/libgee.so.2 (0x00002aaaaaabe000)
        libjson-glib-1.0.so.0 => /lib64/libjson-glib-1.0.so.0 (0x00002aaaaad06000)
        libgobject-2.0.so.0 => /lib64/libgobject-2.0.so.0 (0x0000003a50c00000)
        libglib-2.0.so.0 => /lib64/libglib-2.0.so.0 (0x0000003a50000000)
        libc.so.6 => /lib64/libc.so.6 (0x0000003a4e000000)
        librt.so.1 => /lib64/librt.so.1 (0x0000003a4f400000)
        /lib64/ld-linux-x86-64.so.2 (0x0000003a4dc00000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003a4ec00000)

I know this is more of a GCC issue with linking the shared libraries
at compilation but I am at a loose at what to really do, any help
would be appreciated.
