Hi,

I got the following make related errors when trying to install Xgboost for Python 3.7. I have tried both make and cmake from AIX Toolbox and the error messages are the same. I did search Internet and it seems related to compatibility issue. Can someone help?

Thanks

Mi

Use /opt/freeware/bin/make (GNU make provided by make rpm in Toolbox) instead of AIX /usr/bin/make. 

Hi Ayappan,

Your suggestion works. But I got new error (below). I did some search in Internet and it seems the option is only for Intel platform. Should I just remove the option from some build script in the Xgboost  package and do the pip install again?

Thanks

Mi

g++: error: unrecognized command-line option '-msse2'

Yes, these are x86 specific options. You should remove them while building in AIX. 

Hi Ayappan,

I need help on the following:
1. I see in the CMakeLists.txt file, there is a line as following, I want to add another line right after it to set the value of SUPPORT_MSSE2 as 0. What will be the syntax?

check_cxx_compiler_flag("-msse2"        SUPPORT_MSSE2)

2. I see following lines in the Makefile file. I think adding the leading '#' will disable them?

ifeq ($(USE_SSE), 1)
       CFLAGS += -msse2
endif
 
3. For following error I got during the pip installation, should I set the $CC value to point to /opt/freeware/...?

Makefile:31: MAKE [make] - checked OK
make: cc: No such file or directory
make: cc: No such file or directory 

Thanks

Mi

1) You can set it as blank "" , not sure though.
2) You can comment these things.
3) You can set CC to "/opt/freeware/bin/gcc -pthread -maix64".

Hi Ayappan,

I find once I have modified the *.tar.gz file, the pip installation will no longer succeed. I think that is because the original hashes are no longer valid. So I have tried another version of Xgboost and got the following errors. Maybe making some changes to environment variables resolve the issues? (I have installed libgomp and libgomp10 already)
