Regarding math library linker error

[Madhu Kumar.s.j.]

Hi all,

I am trying to cross compile the lcms2 library for arm64 but I got some below errors related to math library.

/home/madhukumar/TOOL_CHAIN/aarch64-linux-android/bin/../lib/gcc/aarch64-linux-android/4.9.x/../../../../aarch64-linux-android/bin/ld: warning: libm.so, needed by ../../src/.libs/liblcms2.so, not found (try using -rpath or -rpath-link)

clang80: error: linker command failed with exit code 1 (use -v to see invocation)

make[1]: *** [linkicc] Error 1

make[1]: Leaving directory `/home/madhukumar/Libraw/lcms2-2.13/utils/linkicc'

make: *** [all-recursive] Error 1

Any predefined Library is there to link or we need to cross compile that math library also.

If any predefined Library is there to link for cross compling, please suggest me.

Thank you

Hi,

Try to install library

Sudo apt-get install liblcms2-2:i386

Have you linked the math library (-lm), while compiling. If not do it. If yes, check out the hard / soft float related options.
