Question

Anyone manage to write code that uses the mysqlclient library? I can get compiling working but not linking 🙁

XCode produces the following output:

Build TestMysql of project TestMysql with configuration Debug

Ld build/Debug/TestMysql normal x86_64
cd /Users/jacob/Documents/cocoa/TestMysql
setenv MACOSX_DEPLOYMENT_TARGET 10.5
/Developer/usr/bin/gcc-4.2 -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.5.sdk
   -L/Users/jacob/Documents/cocoa/TestMysql/build/Debug -L/usr/local/mysql/lib
   -L/usr/local/mysql-5.1.38-osx10.5-x86_64/lib
   -F/Users/jacob/Documents/cocoa/TestMysql/build/Debug -filelist /Users/jacob/Documents/cocoa/TestMysql/build/TestMysql.build/Debug/TestMysql.build/Objects-normal/x86_64/TestMysql.LinkFileList
   -mmacosx-version-min=10.5 -lm -lz -lmysqlclient -lmygcc "

i686-apple-darwin10-gcc-4.2.1: 
: No such file or directory
Command /Developer/usr/bin/gcc-4.2 failed with exit code 1

And yes I already know about the mysql/cocoa framework, im writing code that must compile on os/x and linux. Ironically it only took me 20 minutes to work out how to write a make file to compile and link and run objective-c / mysql code, but xcode is soo much more complicated.

I believe the “” string is causing you grief — especially since the error message’s filename is the empty string.

Alternate methodology:
Have you considered just using the Makefile you made in XCode?

File->New Project->Other->External Build System.
