could not determine kind of name for C.heif_compression_EVC

[cruvie]

Hi , when I run libheif-master/examples/heif-test.go I encounter this error

package libheif-master/examples: C source files not allowed when not using cgo or SWIG: test_c_api.c

I try to add import "C" and run again encounter this

Can you help me , I have no idea about this and I'm not familiar with C, thank you!

I have the same problem when trying to build my program in docker

I do not know much about go, but these are all new enums. Hence, my guess is that you have an old version of libheif installed in the system and those old headers are used instead of the new libheif version.
