Errors when compiling

[lufinkey]

I'm trying to build this library to include in my build of ffmpeg, and I've been running into some issues.

• The first issue I ran into was that the typeof keyword wasn't defined by the clang compiler. I found I could fix this by adding -std=gnu2x as a flag to CFLAGS.
• The next issue I ran into was that malloc was actually pointing to a macro that defined it as rpl_malloc. I found a stackoverflow post that mentioned this could be fixed by defining ac_cv_func_malloc_0_nonnull=yes and ac_cv_func_realloc_0_nonnull=yes as environment variables.
• The last issue I'm running into is that I get an error about duplicate symbols between run_dummy_icd_through_our_ICDL-run_dummy_icd.o and libOpenCL_la-ocl_icd_loader.o, and between run_dummy_icd_through_our_ICDL-run_dummy_icd_weak_gen.o and libOpenCL_la-ocl_icd_loader_gen.o.

Here are the commands I'm using to build the library:

./bootstrap || return 1

CFLAGS="$CFLAGS -std=gnu2x" \
ac_cv_func_malloc_0_nonnull=yes \
ac_cv_func_realloc_0_nonnull=yes \
./configure \
  --prefix="${LIB_INSTALL_PREFIX}" \
  --enable-pic \
  --with-sysroot="${ANDROID_SYSROOT}" \
  --enable-static \
  --enable-fast-install \
  --disable-shared \
  --disable-debug \
  --host="${HOST}" || return 1

make || return 1

Any help would be much appreciated!

A followup note: if I don't include the --disable-shared flag, I get the error clang: error: no such file or directory: './.libs/libOpenCL.so' when calling make.
