ATS installation error - architecture arm64 not found for libxerces-c-3.2.dylib

[Phong Le]

Hi everyone,

I am encountering an issue while install ATS on my Mac (M1) Sonoma 14.5. Initially, I face a problem with the TPL xerces, specifically a fatal error: 'unicode/uset.h' file not found

To resolve this, I attempted to symlink the unicode header files installed from homebrew to the SDK using the following command:

sudo find /opt/homebrew/Cellar/icu4c/74.2/include/unicode -type f -name "*.h" -exec ln -s {} /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/unicode \;

However, this fix led to another issue still pertaining to the TPL xerces. I ran to an error while linking CXX shared library 'libxerces-c-3.2.dylib', with the following message:

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

make[5]: *** [src/libxerces-c-3.2.dylib] Error 1

make[4]: *** [src/CMakeFiles/xerces-c.dir/all] Error 2

make[3]: *** [all] Error 2

It appears to be an architecture mismatch issue in a C++ shared library. I removed and install CommandLineTools and brew, but it doesn't work.

I have attached the log file and output from the terminal. Any suggestion to resolve this issue is appreciated. Thank you.

So the problem is that Xerces doesn’t realize you are on a mac.  You should have, in your

 

$AMANZI_TPLS_BUILD_DIR/xerces/xerces-X.Y-build/CMakeCache.txt

 

that

 

XERCES_USE_TRANSCODER_MACOSUNICODECONVERTER:BOOL=TRUE

 

But I suspect you have

 

XERCES_USE_TRANSCODER_ICU:BOOL=TRUE

 

instead (which I’m guessing is the default).

 

You could try forcing the issue by changing the CMakeCache.txt file directly, or you could try figuring out why, in

$AMANZI_TPLS_BUILD_DIR/xerces/xerces-X.Y-source/cmake/XercesTranscoderSelection.cmake

 

It fails to match macosunicodecoverter.

Hi Ethan.

This seems right direction. Although I have XERCES_USE_TRANSCODER_MACOSUNICODECONVERTER:BOOL=TRUE in the CMakeCache.txt, the error is that the transcode:STRING was set to icu. I changed it to macosunicodeconverter as below, and now Xerces recognizes the arm64.

//Transcoder (icu|macosunicodeconverter|iconv)

transcoder:STRING=macosunicodeconverter

I ran into other minor issues but I was able to fix them. Finally, ats is installed again on my Mac now.

Thanks Ethan.
