Hello Everybody, I successfully built 1.12 on OSX 10.6.8 with the standard build instructions (./configure, make dep, etc). However, when I step through an OSX application (that is linked with this version of the PJLIB) in XCode (4.2) the debugger does not always proceed step-by-step, but oftentimes jumps backwards a few lines, or skips certain section of my source-code altogether (reproducable). While the OSX app compiles with llvm-gcc-4.2 (since gcc is unsupported with XCode 4.2), it seems that the pjlib compiled with gcc (using the standard instructions). My suspicion is that the object-files/libraries (generated by llvm-gcc-4.2 and gcc) are not compatible enough to be linked correctly - thus, confusing the debugger. I have tried to re-build the pjlib with export CC=/Developer/usr/bin/llvm-gcc-4.2 prior to ./configure. This causes make to terminate with: make[2]: /Developer/usr/bin/llvm--4.2ar: No such file or directory make[2]: *** [../lib/libpj-i386-apple-darwin10.8.0.a] Error 1 make[1]: *** [pjlib] Error 2 make: *** [all] Error 1 Has anybody encountered this problem and/or knows how to correctly build the pjlib for OSX using llvm-gcc-4.2 ? Thanks in advance. Best regards, Thomas
