You have a problem with the way libgit2 is compiled. It references symbols that do not exist in libiconv. On OS X, all symbols are prefixed by ‘iconv’ not ‘libiconv’ (iconv_close, iconv_open, …)
Make sure you use the system libiconv headers when compiling libgit2. > Le 8 nov. 2014 à 17:07, David Catmull <[email protected]> a écrit : > >> >> On Nov 8, 2014, at 1:14 AM, Jean-Daniel Dupas <[email protected] >> <mailto:[email protected]>> wrote: >> >> Can you give as the transcript. >> >> What is the compiler invocation command, and exact error message ? > > Here's the log: > >> Ld >> /Users/uncommon/Developer/Xit/DerivedData/Xit/Build/Products/Debug/ObjectiveGit.framework/Versions/A/ObjectiveGit >> normal x86_64 >> cd /Users/uncommon/Developer/Xit/objective-git >> export MACOSX_DEPLOYMENT_TARGET=10.7 >> >> /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang >> -arch x86_64 -dynamiclib -isysroot >> /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk >> -L/Users/uncommon/Developer/Xit/DerivedData/Xit/Build/Products/Debug -L. >> -LExternal >> -F/Users/uncommon/Developer/Xit/DerivedData/Xit/Build/Products/Debug >> -filelist >> /Users/uncommon/Developer/Xit/DerivedData/Xit/Build/Intermediates/ObjectiveGitFramework.build/Debug/ObjectiveGit.build/Objects-normal/x86_64/ObjectiveGit.LinkFileList >> -install_name @rpath/ObjectiveGit.framework/ObjectiveGit >> -mmacosx-version-min=10.7 -lgit2 -force_load External/libgit2.a >> /usr/local/lib/libssh2.a -lcrypto -lssl -fobjc-arc -fobjc-link-runtime >> -liconv -framework Cocoa -lz -single_module -compatibility_version 1 >> -current_version 1 -Xlinker -dependency_info -Xlinker >> /Users/uncommon/Developer/Xit/DerivedData/Xit/Build/Intermediates/ObjectiveGitFramework.build/Debug/ObjectiveGit.build/Objects-normal/x86_64/ObjectiveGit_dependency_info.dat >> -o >> /Users/uncommon/Developer/Xit/DerivedData/Xit/Build/Products/Debug/ObjectiveGit.framework/Versions/A/ObjectiveGit >> >> Undefined symbols for architecture x86_64: >> "_libiconv", referenced from: >> _git_path_iconv in libgit2.a(path.c.o) >> "_libiconv_close", referenced from: >> _git_path_iconv_clear in libgit2.a(path.c.o) >> "_libiconv_open", referenced from: >> _git_path_iconv_init_precompose in libgit2.a(path.c.o) >> ld: symbol(s) not found for architecture x86_64 >> clang: error: linker command failed with exit code 1 (use -v to see >> invocation) > > > >> >>> Le 7 nov. 2014 à 01:51, David Catmull <[email protected]> a écrit : >>> >>> On one of my computers, I've started getting a strange error when building >>> Objective Git - the linker claims that libiconv (which is in /usr/lib) >>> can't be found.
