Description
Latest working version is https://code.qt.io/cgit/qt-creator/qt-creator.git/commit/?id=448446bd7ed40e1adbd1b66cdf92e50a125da5f3, next commit https://code.qt.io/cgit/qt-creator/qt-creator.git/commit/?id=9c3420120ea9b477a8677de667e0b3dc5375159b doesn't work. Tested also on latest commit in 7.0 branch https://code.qt.io/cgit/qt-creator/qt-creator.git/commit/?h=7.0&id=2090d043db2991af964a546cebf39c996b7236c5
In the test project we have a configurable file:
define.h.in
#define TEST_IMPORT @TEST_IMPORT@ #define TEST_EXPORT @TEST_EXPORT@
We configure it:
set(DEFINE_HEADER ${CMAKE_CURRENT_BINARY_DIR}/define.h)
set(TEST_IMPORT "")
set(TEST_EXPORT "__attribute__ ((visibility(\"default\")))")
configure_file(define.h.in "${DEFINE_HEADER}" @ONLY)
and include it everywhere with a compiler option:
add_compile_options(-include "${DEFINE_HEADER}")
We also set CMake property to use either import or export definition as Module_EXPORT define:
set_target_properties(TestQtCreatorExport PROPERTIES
INTERFACE_COMPILE_DEFINITIONS "Module_EXPORT=TEST_IMPORT"
COMPILE_DEFINITIONS "Module_EXPORT=TEST_EXPORT")
In the code we use this define:
Test.h
class Module_EXPORT Test;
With old version this works, recent versions produces error:
/home/nkrupenko/Development/TestQtCreatorExport/Test.h:4: error: Variable has incomplete type 'class TEST_EXPORT' /home/nkrupenko/Development/TestQtCreatorExport/Test.h:4: Forward declaration of 'TEST_EXPORT'
Attached full test project.
