1691	Error in 008-z-libxslt during blfs-tool build in jhalfs	shane87	alfs-log@…	"While building LFS-7.5 using jhalfs, I continuously hit an error during the blfs-tool phase. The specific error reported in the terminal is:

{{{

}}}

Checking the logs in /mnt/build_dir/blfs_root/work/logs/008-z-libxslt, I see that the specific error during the build is:

{{{

After doing some searching, I have found that the error is caused by Python not being able to locate an xml parser module. From what I have read, and tested, the easiest way to fix this is to build and install expat before configuring and building Python. To confirm expat fixes the issue, I entered the chroot jail manually and installed expat, following the instructions from blfs. Then I re-ran the jhalfs tool, which successfully completed the entire build, including the blfs-tools phase, and 008-z-libxslt compiled perfectly.

What really strikes me as odd is that the blfs-tool does not pick up Python's recommended expat dependency. It builds libffi, which is also a recommended dependency for Python, but expat is not picked up.

I am attaching the log from my build of libxslt (/mnt/build_dir/blfs_root/work/logs/008-z-libxslt), the SBU_DU report from my jhalfs build (for complete system info), and the build log from the install of Python (/mnt/build_dir/blfs_root/work/logs/003-z-python)"	defect	closed	normal		jhalfs	SVN	normal	wontfix	blfs-tool, libxslt, expat
