From 2eb1844990609fdf1c7d4c66e4f5a1dd397cd816 Mon Sep 17 00:00:00 2001 From: "Scott J. Goldman" Date: Sat, 26 May 2012 18:20:33 -0700 Subject: [PATCH] Refactor CMakeLists.txt for mingw cross-compile Two things: 1) By default, Linux CMake puts -fPIC on the link line. So we remove that for MINGW to avoid warnings that it will be ignored. 2) Similarly, move -fvisibility=hidden flag to be for non-mingw compilation only to avoid warnings that it will be ignored. --- CMakeLists.txt | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 165baba78..8018ea72d 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -71,10 +71,12 @@ IF (MSVC) # Precompiled headers ELSE () - SET(CMAKE_C_FLAGS "-O2 -g -D_GNU_SOURCE -fvisibility=hidden -Wall -Wextra -Wno-missing-field-initializers -Wstrict-aliasing=2 -Wstrict-prototypes -Wmissing-prototypes ${CMAKE_C_FLAGS}") + SET(CMAKE_C_FLAGS "-O2 -g -D_GNU_SOURCE -Wall -Wextra -Wno-missing-field-initializers -Wstrict-aliasing=2 -Wstrict-prototypes -Wmissing-prototypes ${CMAKE_C_FLAGS}") SET(CMAKE_C_FLAGS_DEBUG "-O0 -g") - IF (NOT MINGW) # MinGW always does PIC and complains if we tell it to - SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fPIC") + IF (MINGW) # MinGW always does PIC and complains if we tell it to + STRING(REGEX REPLACE "-fPIC" "" CMAKE_SHARED_LIBRARY_C_FLAGS "${CMAKE_SHARED_LIBRARY_C_FLAGS}") + ELSE () + SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fvisibility=hidden -fPIC") ENDIF () IF (PROFILE) SET(CMAKE_C_FLAGS "-pg ${CMAKE_C_FLAGS}")
