From 449f343498b4524a38c3a6fb6b2e9e1753144c5d Mon Sep 17 00:00:00 2001 From: Axel Huebl Date: Mon, 14 Feb 2022 12:42:58 -0800 Subject: FindHDF5: Tolerate failure during compiler interrogation Check that the file that is accessed via `file(STRINGS...)` truly exists. This is not the case in some EMSCRIPTEN/WebASM builds where we want to overwrite the HDF5 find logic manually. The missing check here prevents that one can overwrite the search logic in exotic environments. --- Modules/FindHDF5.cmake | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Modules/FindHDF5.cmake b/Modules/FindHDF5.cmake index 9123d56292..40ed9a92c8 100644 --- a/Modules/FindHDF5.cmake +++ b/Modules/FindHDF5.cmake @@ -242,7 +242,7 @@ function(_HDF5_test_regular_compiler_C success version is_parallel) COPY_FILE ${scratch_directory}/compiler_has_h5_c ) endif() - if(${success}) + if(${success} AND EXISTS ${scratch_directory}/compiler_has_h5_c) file(STRINGS ${scratch_directory}/compiler_has_h5_c INFO_STRINGS REGEX "^INFO:" ) @@ -290,7 +290,7 @@ function(_HDF5_test_regular_compiler_CXX success version is_parallel) COPY_FILE ${scratch_directory}/compiler_has_h5_cxx ) endif() - if(${success}) + if(${success} AND EXISTS ${scratch_directory}/compiler_has_h5_cxx) file(STRINGS ${scratch_directory}/compiler_has_h5_cxx INFO_STRINGS REGEX "^INFO:" ) -- cgit v1.2.1
