Xcode build problem

Hi, all,

I have a (large) C++ tool I am trying to build. I want to build with a special version of a library, so I changed it in the project view, with a new path. If I "get info" on the library, it shows the proper path.

Xcode produces the following link command:

/usr/bin/g++-3.3 -o /Volumes/SandBox/Justin/NumberTheory/MFC/build/hecke "-L/Volumes/SandBox/Justin/NumberTheory/MFC/build" "-L/usr/local/lib" "-L/Volumes/SandBox/Justin/NumberTheory/MFC/LiDIA-2.1.3/library/.libs" "-F/Volumes/SandBox/Justin/NumberTheory/MFC/build" -filelist /Volumes/SandBox/Justin/NumberTheory/MFC/build/hecke.build/hecke.build/ Objects-normal/LinkFileList "-arch" "ppc" "-prebind" "-Wl,-no_arch_warnings" "-lLiDIA" "-lgmp" "-lntl" "-lstdc++" "-lLiDIA"

and this appears to get the copy of libLiDIA.a that lives in /usr/local/lib (rdar://4084480).

The following modified link command seems to do the trick (as I understand "-L", it affects the libraries up to the next "-L", but I don't know the effect of multiple sequential "-L"s (it appears to be "check the first -L; then the next; then ..."):

/usr/bin/g++-3.3 -o /Volumes/SandBox/Justin/NumberTheory/MFC/build/hecke "-L/Volumes/SandBox/Justin/NumberTheory/MFC/build" "-L/Volumes/SandBox/Justin/NumberTheory/MFC/LiDIA-2.1.3/library/.libs" "-F/Volumes/SandBox/Justin/NumberTheory/MFC/build" -filelist /Volumes/SandBox/Justin/NumberTheory/MFC/build/hecke.build/hecke.build/ Objects-normal/LinkFileList "-arch" "ppc" "-prebind" "-Wl,-no_arch_warnings" "-lLiDIA" "-L/usr/local/lib" "-lgmp" "-lntl" "-lstdc++"

Anyone know how I can persuade Xcode to put the "-L"s in the right places?

Thanks for the help!

Regards,

Justin
