Compiling problem on aarch64 platform

[v2aus]

Hello, when I compile the source code on aarch64 platform with g++ 8.5.0. The compiler gives out the error information below:

[ 3%] Building CXX object CMakeFiles/open_htj2k.dir/source/core/codestream/j2kmarkers.cpp.o In file included from /home/centos/OpenHTJ2K-0.2.1-origin/source/core/codestream/codestream.hpp:37, from /home/centos/OpenHTJ2K-0.2.1-origin/source/core/codestream/j2kmarkers.hpp:34, from /home/centos/OpenHTJ2K-0.2.1-origin/source/core/codestream/j2kmarkers.cpp:29: /home/centos/OpenHTJ2K-0.2.1-origin/source/core/common/utils.hpp:62:41: error: variable or field ‘_mm256_storeu2_m128i’ declared void static inline void _mm256_storeu2_m128i(m128i_u* __addr_hi, m128i_u addr_lo, m256i a) { ^~~~~ /home/centos/OpenHTJ2K-0.2.1-origin/source/core/common/utils.hpp:62:41: error: ‘__m128i_u’ was not declared in this scope /home/centos/OpenHTJ2K-0.2.1-origin/source/core/common/utils.hpp:62:52: error: ‘addr_hi’ was not declared in this scope static inline void _mm256_storeu2_m128i(__m128i_u addr_hi, __m128i_u* addr_lo, m256i a) { ^~~~~ /home/centos/OpenHTJ2K-0.2.1-origin/source/core/common/utils.hpp:62:52: note: suggested alternative: ‘caddr_t’ static inline void _mm256_storeu2_m128i(m128i_u __addr_hi, __m128i_u addr_lo, m256i a) { ^~~~~ __caddr_t /home/centos/OpenHTJ2K-0.2.1-origin/source/core/common/utils.hpp:62:63: error: ‘m128i_u’ was not declared in this scope static inline void _mm256_storeu2_m128i(m128i_u* __addr_hi, m128i_u __addr_lo, m256i a) { ^~~~~ /home/centos/OpenHTJ2K-0.2.1-origin/source/core/common/utils.hpp:62:74: error: ‘addr_lo’ was not declared in this scope static inline void _mm256_storeu2_m128i(m128i_u addr_hi, __m128i_u* addr_lo, m256i a) { ^~~~~ /home/centos/OpenHTJ2K-0.2.1-origin/source/core/common/utils.hpp:62:74: note: suggested alternative: ‘caddr_t’ static inline void _mm256_storeu2_m128i(m128i_u __addr_hi, __m128i_u addr_lo, m256i a) { ^~~~~ __caddr_t /home/centos/OpenHTJ2K-0.2.1-origin/source/core/common/utils.hpp:62:85: error: ‘m256i’ was not declared in this scope static inline void _mm256_storeu2_m128i(m128i_u* __addr_hi, m128i_u* __addr_lo, m256i a) {

and the cmake output information is:

Thank you for reporting this issue. b021173 may fix this problem. Could you try fix_utils branch?

I compiled the 0.2.2 version. And I met another problem:

[ 80%] Linking CXX shared library bin/libopen_htj2k_R.so [ 80%] Built target open_htj2k [ 83%] Building CXX object CMakeFiles/open_htj2k_dec.dir/source/apps/decoder/main_dec.cpp.o [ 87%] Linking CXX executable bin/open_htj2k_dec bin/libopen_htj2k_R.so: undefined reference to typeinfo for std::filesystem::__cxx11::filesystem_error' bin/libopen_htj2k_R.so: undefined reference tostd::filesystem::cxx11::path::_M_split_cmpts()' bin/libopen_htj2k_R.so: undefined reference to `std::filesystem::file_size(std::filesystem::cxx11::path const&)' collect2: error: ld returned 1 exit status make[2]: [CMakeFiles/open_htj2k_dec.dir/build.make:98: bin/open_htj2k_dec] Error 1 make[1]: [CMakeFiles/Makefile2:232: CMakeFiles/open_htj2k_dec.dir/all] Error 2 make: *** [Makefile:146: all] Error 2

I googled, and I found the solution, which is adding below code into CmakeLists.txt file:

target_link_libraries(open_htj2k PUBLIC stdc++fs)
