Greetings
For various reasons, I can't install the RPMs for TigerVNC on my EL6 system.
So I am trying to build from source.
I have downloaded and installed cmake 2.8.12 from source.
I then downloaded and patched fltk 1.3.2.
The TigerVNC instructions say to use cmake to build fltk, however when I do,
the make phase ends like so:
[ 96%] Built target tabs
Linking CXX executable ../bin/examples/threads
CMakeFiles/threads.dir/threads.cxx.o: In function `fl_create_thread(unsigned
long&, void* (*)(void*), void*)':
threads.cxx:(.text+0x29): undefined reference to `pthread_create'
collect2: ld returned 1 exit status
make[2]: *** [bin/examples/threads] Error 1
make[1]: *** [test/CMakeFiles/threads.dir/all] Error 2
make: *** [all] Error 2
If I ignore the instructions and do a more traditional ./configure ; make ;
make install for fltk, it builds and installs. However, the vncviewer build
then dies with
[100%] Building CXX object
vncviewer/CMakeFiles/vncviewer.dir/X11PixelBuffer.cxx.o

I have libpng-devel installed.
Can anyone tell me what I am doing wrong?
