That's fine if you're using a C++ compiler to build it as a static
library - but on Linux lcms is built (in C mode) as a shared library.
To link that with a C++ project, the C++ compiler needs to know that the
library functions should be called with C name-mangling and calling
conventions. Without adding the extern "C" { } construct I could
compile just fine, but got loads of undefined symbol errors when linking.
(Adding that construct to the C++ project is no hardship, mind you - as
long as the need for it is documented)
Speaking of libraries and linking, is there any chance the name of the
library itself could be changed to lcms2 (to match the header file) or
something similar?
That would allow both LCMS1 and 2 to be installed and linkable
simultaneously.
As it currently stands, if you install LCMS2 from source on Linux, the
liblcms.so symlink will be changed to point to LCMS2, and it will no
longer be possible to build software against LCMS1!
All the best,
