From: Zhang Peng <[email protected]>
When building the `lapack` package, the following QA error occurs:
"File /usr/lib64/libblas.so.3.12.0 in package lapack contains reference to
TMPDIR [buildpaths]"
The issue arises because the `xerbla.o` object file embeds the absolute host
path of `xerbla.f`.
This occurs during compilation, where the build command in `build.make`
(generated by CMake) specifies:
`gfortran -c <absolute path>/xerbla.f -o`.
As a result, the absolute path is included in `xerbla.o`. Unfortunately,
`gfortran` does not support
flags like `-fdebug-prefix-map` or `-ffile-prefix-map` to remove such paths.
To resolve this, the fix involves replacing the absolute path of `xerbla.f` in
the generated
`build.make` file with a relative path before the compilation step. This
ensures that the
resulting `xerbla.o` does not contain any references to TMPDIR, passing the
`do_package_qa` check.
For ptest code, the solution is to replace `${WORKDIR}` with `../../..` in the
generated `build.make`
files located in the TESTING directory.

+# This workaround resolves the TMPDIR [buildpaths] issue by converting the
absolute path
+# of `xerbla.f` to a relative path. The steps are as follows:
+#
+# 1. Locate all `build.make` files after the `do_configure` step is completed.
+# 2. Compute the relative path for `xerbla.f` based on the current build
directory.
+# 3. Replace the absolute path with the calculated relative path in the
`build.make` files
+#
+# Additionally, when ptests are enabled, apply a simpler workaround for ptest
code:
+# - Replace occurrences of `${WORKDIR}` in all `build.make` files under the
TESTING directory, excluding
+# the MATGEN subdirectory, with a relative path prefix of `"../../.."`.
