As the message says, you don't have the X11 development environment installed.
I suggest you dig out the Xcode installer.
What are you trying to build anyway, most open source code that does anything with shared libraries collapses in a heap when trying to compile on Darwin.
I suggest you look at Fink or similar for patches to build code on Darwin.
Hi porter, could you please give me a bit more information on what I should do as I'm absolutely stupid on this...
I installed fink but like, it couldn't install anything, whatever I tried to install it just gave me thousands of compiling errors... So I gave up on fink, but still got the same problem of not having x11 development environment... where can i find it???
Hi porter! Thank you very much for your help. I have read through that instruction and installed XFree86 successfully following the instruction on Installation Details for XFree86� 4.5.0.
But after I downloaded the X11.app and tried to install X11 on my computer, it gave me:
"you cannot install X11 on this volume, newer software already exists on your computer."
I tried to install gtk+ again, instead of the previous error, it gave me something else:
"checking for XOpenDisplay... no
configure: error: *** libX11 not found. Check 'config.log' for more details."
Any ideas??? Thanks very very very very very much!!!!!!!!!!!!!!!!!!!!!
