NAK, breaks Linux sw-only mangled mesa build.
My command line to create the exports file ends up being:
gcc -E -I ../../../include/GL -g -DUSE_MGL_NAMESPACE -Wall
-Wmissing-prototypes -std=c99 -ffast-math -fno-strict-aliasing -fPIC
-DUSE_X86_64_ASM -D_GNU_SOURCE -DPTHREADS -DHAVE_POSIX_MEMALIGN
-DUSE_XSHM glu.exports.in | \
awk '/^[^#]+/ {print}' > glu.exports
which complains:
gcc: glu.exports.in: linker input file unused because linking not done
If I manually invoke:
cpp -E glu.exports.in | awk '/^[^#]+/ {print}' > glu.exports
it does the right thing, and the build works thereafter.
FYI, compiler:
t...@shigeru mesa gcc -v 2>&1 | grep "gcc version"
gcc version 4.3.2 (Debian 4.3.2-1.1)
I like the approach though. Might be a good idea to do something like
this for Darwin as well, so we could unify the way the export table is
built.
