Error if CMake tries to configure with read-only source directory
We maintain our internal test suites under Perforce. We have a test suite that builds and tests ScaLAPACK with the NVHPC compilers.
Our suite runs CMake in a separate directory from the source tree, which is stored in the source repo with read-only permissions. When CMake runs this way, we see the following error:
CMake Error: Unable to (re)create the private pkgRedirects directory:
/proj/ta/tests/techtips_repo/src/scalapack-2.2.2/BLACS/INSTALL/CMakeFiles/pkgRedirects
This may be caused by not having read/write access to the build directory.
Try specifying a location with read/write access like:
cmake -B build
If using a CMake presets file, ensure that preset parameter
'binaryDir' expands to a writable directory.
CMake Error at CMAKE/FortranMangling.cmake:33 (MESSAGE):
Configure in the BLACS INSTALL directory FAILED
Call Stack (most recent call first):
CMakeLists.txt:133 (COMPILE)
-- Configuring incomplete, errors occurred!
I am working around this for the moment by copying the source tree to a writable location. However, would you consider reworking this to allow configuration against a read-only source tree? Thanks in advance.
Can you expand on what the configure command was used, and is it reproducible with the latest branch (I don't think I've touched that, so maybe it still is). It might be resolved after having bumped the CMake policies though.
This still seems to be a problem with a TOT pull of ScaLAPACK from github:
