Compiling on a M1 Mac

[jianshu93]

Dear StrobeAlign,

I cannot compile it on a M1 pro chip (ARM), something like -O3 -march=armv8. Any possibilities to also provide a binary?

THanks,

Jianshu

This will be the first thing I try whenever I can get a hold of a MacBook with M1 chip.

What is the compilation error?

[jianshu93]

Hi Check this on M1:

Jianshus-MBP-2:StrobeAlign jianshuzhao$ g++ -std=c++14 main.cpp source/index.cpp source/ksw2_extz2_sse.c -lz -fopenmp -o StrobeAlign -O3 -march=armv8.5-a Undefined symbols for architecture arm64: "_ksw_extz2_sse", referenced from: __Z9ksw_alignPKciS0_iiiiiR10ksw_extz_t in ccdGVhMg.o ld: symbol(s) not found for architecture arm64 collect2: error: ld returned 1 exit status

Thanks,

Jianshu

Hi @jianshu93 ,

I realized that strobealign is no longer using ksw2. I made a commit to develop that disables it https://github.com/ksahlin/StrobeAlign/commit/706ebb972552ec34a23d8003aa81eb3d097017aa

Since the error you reported is due to the ksw2 lib, it may be possible to compile the develop commit (https://github.com/ksahlin/StrobeAlign/commit/706ebb972552ec34a23d8003aa81eb3d097017aa) with

g++ -std=c++14 main.cpp source/index.cpp  source/xxhash.c source/ssw_cpp.cpp  source/ssw.c source/pc.cpp source/aln.cpp -lz -lpthread -o strobealign -O3 -mavx2

Would be cool if you could verify whether it compiles whenever you have time.

Hello @ksahlin ,

See below:

g++ -std=c++14 main.cpp source/index.cpp source/xxhash.c source/ssw_cpp.cpp source/ssw.c source/pc.cpp source/aln.cpp -lz -lpthread -o strobealign -O3 -march=armv8.4-a In file included from source/ssw_cpp.cpp:6: source/ssw.h:17:10: fatal error: emmintrin.h: No such file or directory 17 | #include <emmintrin.h> | ^~~~~~~~~~~~~ compilation terminated. source/ssw.c:70:10: fatal error: emmintrin.h: No such file or directory 70 | #include <emmintrin.h> | ^~~~~~~~~~~~~ compilation terminated.

I think the head saw.h relies on, emmintrin.h can be replaced by some of the headers mentioned by @sjaenick.

Thanks,

Jianshu

Great @jianshu93. I will order such a MacBook to look at this first-hand.

[jianshu93]

You will love it! Everything is 3-5 times faster than an intel version, BWA-MEM neon version is 3.5 faster than an intel avx2 version on average. I believe strobealign will be amazingly fast on an M1 Mac, maybe even faster than a 24 threads computer cluster.

Just trying this out on an M1 macbook compiling in CLion and I run into the same thing. The intrinsics in SSW lib is only meant for x86 and x64 architectures.

@marcelm is this possible adding support for (and if so, is it worth it)? Was thinking now that strobealign's peak memory may be laptop friendly soon.

I don’t have access to an M1 Mac, so I think I cannot help too much with this. Two options come to mind:

1. Use sse2neon, which translates from x86 SSE instructions to the SIMD instructions used on the M1 processor.
2. Compile to an x86_64 binary and rely on the x86-64 emulation that I heard is built into macOS.

Alright, thanks for input. I see if I'll get around to try option 1 myself.
