Hello,
Just a note, recently I download lcms 1.17 for compile it under Mac OS
10.5.2 and XCode 2.5 on a PowerMac G4.
1) I notice the library name is incorrect, it is liblcms.1.0.16.dylib.
For lcms version 1.17, the library name should be liblcms.
1.0.17.dylib, right ?
xyz:.libs pchan$ pwd
/Users/pchan/Project-Lib/lcms-1.17/src/.libs
isidualg4:.libs pchan$ ls -als liblcms.*
448 -rwxr-xr-x 1 pchan staff 227096 Apr 23 09:32 liblcms.
1.0.16.dylib
8 lrwxr-xr-x 1 pchan staff 20 Apr 23 09:32 liblcms.1.dylib -
> liblcms.1.0.16.dylib
1648 -rw-r--r-- 1 pchan staff 842208 Apr 23 09:32 liblcms.a
8 lrwxr-xr-x 1 pchan staff 20 Apr 23 09:32 liblcms.dylib ->
liblcms.1.0.16.dylib
8 lrwxr-xr-x 1 pchan staff 13 Apr 23 09:32 liblcms.la -> ../
liblcms.la
8 -rw-r--r-- 1 pchan staff 811 Apr 23 09:32 liblcms.lai
xyz:.libs pchan$
2) I copy and ranlib liblcms.a file into a simple test project. The
test project compile but the linker failed, spitting error messages,
see below. Later I boot up Mac OS 10.4 (Tiger) on another machine,
also using XCode 2.5, recompile lcms 1.17 and do the same step for the
test project. No compilation error on tiger.
