From 4dc4018553856fb2dae47ea608b8a09221b155fa Mon Sep 17 00:00:00 2001 From: Brad King Date: Wed, 17 Jul 2013 14:56:40 -0400 Subject: Teach compiler ABI check to tolerate try_compile COPY_FILE failure In CMakeDetermineCompilerABI we use try_compile with the COPY_FILE option to get a copy of the compiled binary used to detect the ABI information. We already tolerate the case when compilation fails. However, when compilation appears to succeed but does not produce the expected executable the try_compile command immediately reports an error because the COPY_FILE fails. Tolerate COPY_FILE failure without stopping the overall configuration process by using the try_compile COPY_FILE_ERROR option to capture the error message. Log the full error to CMakeError.log and simply report failure to detect the ABI as if compilation had failed. Teach the RunCMake.Configure test to cover this case and verify that the messages show up as expected both in stdout and in CMakeError.log. --- Modules/CMakeDetermineCompilerABI.cmake | 5 +++-- Tests/RunCMake/Configure/FailCopyFileABI-check.cmake | 13 +++++++++++++ Tests/RunCMake/Configure/FailCopyFileABI-override.cmake | 6 ++++++ Tests/RunCMake/Configure/FailCopyFileABI-stdout.txt | 4 ++++ Tests/RunCMake/Configure/FailCopyFileABI.cmake | 2 ++ Tests/RunCMake/Configure/RunCMakeTest.cmake | 1 + 6 files changed, 29 insertions(+), 2 deletions(-) create mode 100644 Tests/RunCMake/Configure/FailCopyFileABI-check.cmake create mode 100644 Tests/RunCMake/Configure/FailCopyFileABI-override.cmake create mode 100644 Tests/RunCMake/Configure/FailCopyFileABI-stdout.txt create mode 100644 Tests/RunCMake/Configure/FailCopyFileABI.cmake diff --git a/Modules/CMakeDetermineCompilerABI.cmake b/Modules/CMakeDetermineCompilerABI.cmake index 44cc04a..e9ae995 100644 --- a/Modules/CMakeDetermineCompilerABI.cmake +++ b/Modules/CMakeDetermineCompilerABI.cmake @@ -41,6 +41,7 @@ function(CMAKE_DETERMINE_COMPILER_ABI lang src) "--no-warn-unused-cli" OUTPUT_VARIABLE OUTPUT COPY_FILE "${BIN}" + COPY_FILE_ERROR _copy_error ) # Move result from cache to normal variable. set(CMAKE_${lang}_ABI_COMPILED ${CMAKE_${lang}_ABI_COMPILED}) @@ -48,7 +49,7 @@ function(CMAKE_DETERMINE_COMPILER_ABI lang src) set(CMAKE_${lang}_ABI_COMPILED ${CMAKE_${lang}_ABI_COMPILED} PARENT_SCOPE) # Load the resulting information strings. - if(CMAKE_${lang}_ABI_COMPILED) + if(CMAKE_${lang}_ABI_COMPILED AND NOT _copy_error) message(STATUS "Detecting ${lang} compiler ABI info - done") file(APPEND ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeOutput.log "Detecting ${lang} compiler ABI info compiled with the following output:\n${OUTPUT}\n\n") @@ -131,7 +132,7 @@ function(CMAKE_DETERMINE_COMPILER_ABI lang src) else() message(STATUS "Detecting ${lang} compiler ABI info - failed") file(APPEND ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeError.log - "Detecting ${lang} compiler ABI info failed to compile with the following output:\n${OUTPUT}\n\n") + "Detecting ${lang} compiler ABI info failed to compile with the following output:\n${OUTPUT}\n${_copy_error}\n\n") endif() endif() endfunction() diff --git a/Tests/RunCMake/Configure/FailCopyFileABI-check.cmake b/Tests/RunCMake/Configure/FailCopyFileABI-check.cmake new file mode 100644 index 0000000..c439aac --- /dev/null +++ b/Tests/RunCMake/Configure/FailCopyFileABI-check.cmake @@ -0,0 +1,13 @@ +set(log "${RunCMake_TEST_BINARY_DIR}/CMakeFiles/CMakeError.log") +if(EXISTS "${log}") + file(READ "${log}" error_log) +else() + set(error_log "") +endif() +if(NOT error_log MATCHES "Cannot copy output executable.* +to destination specified by COPY_FILE:.* +Unable to find the executable at any of: + .*\\.missing") + string(REGEX REPLACE "\n" "\n " error_log " ${error_log}") + set(RunCMake_TEST_FAILED "Log file:\n ${log}\ndoes not have expected COPY_FILE failure message:\n${error_log}") +endif() diff --git a/Tests/RunCMake/Configure/FailCopyFileABI-override.cmake b/Tests/RunCMake/Configure/FailCopyFileABI-override.cmake new file mode 100644 index 0000000..c633555 --- /dev/null +++ b/Tests/RunCMake/Configure/FailCopyFileABI-override.cmake @@ -0,0 +1,6 @@ +# Change the executable suffix that try_compile will use for +# COPY_FILE but not inside the test project.
