I tried to emerge gemsvnc and received a compile error. In addition, after patching the ebuild, gemsvnc fails to work with any pixel resolution other than 32 bits per pixel. Reproducible: Always Steps to Reproduce: 1. emerge gemsvnc 2. patch the ebuild to #include <unistd.h> 3. emerge gemsvnc 4. run gemsvnc when X is running at 16 bpp 5. use some vncviewer to connect to gemsvnc Actual Results: I reveived the following during building: >>> md5 src_uri ;-) gemsvnc-1.tbz2 >>> Unpacking source... >>> Unpacking gemsvnc-1.tbz2 to /var/tmp/portage/gemsvnc-1/work >>> Source unpacked. g++ -march=pentium3 -O2 -pipe -I/usr/include/rfb -DHAVE_PTHREADS -c commands.c g++ -march=pentium3 -O2 -pipe -I/usr/include/rfb -DHAVE_PTHREADS -c ilace.c g++ -march=pentium3 -O2 -pipe -I/usr/include/rfb -DHAVE_PTHREADS -c rectangle.c g++ -march=pentium3 -O2 -pipe -I/usr/include/rfb -DHAVE_PTHREADS -c cmd_sockets.c g++ -march=pentium3 -O2 -pipe -I/usr/include/rfb -DHAVE_PTHREADS -c gemsvnc.car -rc locallib.a commands.o ilace.o rectangle.o cmd_sockets.o gemsvnc.c: In function `int main(int, char**)': gemsvnc.c:1438: `fork' undeclared (first use this function) gemsvnc.c:1438: (Each undeclared identifier is reported only once for each function it appears in.) gemsvnc.c:1439: `setsid' undeclared (first use this function) gemsvnc.c:1441: `chdir' undeclared (first use this function) gemsvnc.c:1442: `close' undeclared (first use this function) make: *** [gemsvnc.o] Error 1 !!!

Expected Results: The build should have completed properly in the first case, and the display should have been correct in the second case. I have patched the ebuild for both problems.

Created attachment 23046 [details] Patched ebuild to fix described problems
i added the include patch ... i dont have any 16 bit servers laying around so i'll have to play with that in a bit
as far as i can tell, this is an upstream bug ... fixing this is a little beyond me and not really worth the time i dont think ... in the meantime, i'd suggest x11vnc that comes with the libvncserver package ... it's pretty much on par with gemsvnc now sorry :/
someone else fixed it for me :)
2-r1 fixes this bpp issues (see Bug 45845)
