#2336 gmsh library not loaded in the packaged pex python binary Issue created by msavtchouk-pf I use pants package to get a .pex python binary. In requirements file I have a dependency:

gmsh==4.12.1

When I execute the binary, I see the following problem

Warning: could not find Gmsh shared library libgmsh.so.4.12 with ctypes.util.find_library() or in the following locations: ['/root/.pex/installed_wheels/5b4820c98b3a9fff6fe08010f8dfd52a77ca6ecc46b0a1212245061298862c60/gmsh-4.12.1-py2.py3-none-manylinux_2_24_x86_64.whl/libgmsh.so.4.12', '/root/.pex/installed_wheels/5b4820c98b3a9fff6fe08010f8dfd52a77ca6ecc46b0a1212245061298862c60/gmsh-4.12.1-py2.py3-none-manylinux_2_24_x86_64.whl/lib/libgmsh.so.4.12', '/root/.pex/installed_wheels/5b4820c98b3a9fff6fe08010f8dfd52a77ca6ecc46b0a1212245061298862c60/gmsh-4.12.1-py2.py3-none-manylinux_2_24_x86_64.whl/Lib/libgmsh.so.4.12', '/root/.pex/installed_wheels/5b4820c98b3a9fff6fe08010f8dfd52a77ca6ecc46b0a1212245061298862c60/libgmsh.so.4.12', '/root/.pex/installed_wheels/5b4820c98b3a9fff6fe08010f8dfd52a77ca6ecc46b0a1212245061298862c60/lib/libgmsh.so.4.12', '/root/.pex/installed_wheels/5b4820c98b3a9fff6fe08010f8dfd52a77ca6ecc46b0a1212245061298862c60/Lib/libgmsh.so.4.12', '/root/.pex/installed_wheels/libgmsh.so.4.12', '/root/.pex/installed_wheels/lib/libgmsh.so.4.12', '/root/.pex/installed_wheels/Lib/libgmsh.so.4.12']
When I expect the mentioned directory  '/root/.pex/installed_wheels/5b4820c98b3a9fff6fe08010f8dfd52a77ca6ecc46b0a1212245061298862c60/gmsh-4.12.1-py2.py3-none-manylinux_2_24_x86_64.whl

I can see indeed that the library is not in the root directory or

/lib

subdir. It is in a

/.prefix/lib

subdir. In the root dir there is a

.layout.json

file located. Contents are

{"record_relpath": "gmsh-4.12.1.dist-info/RECORD", "stash_dir": ".prefix"}

Reproducible on Ubuntu with

pants help pex-cli

2.1.137 pantsbuild/pex
