From 7e246e6aa63979d53731a591f4caee3651c1d96b Mon Sep 17 00:00:00 2001 From: Luca Barbieri Date: Tue, 23 Mar 2010 21:10:07 +0100 Subject: dri: make unresolved symbol test link work even without a libGL.so Currently the test link uses -lGL to define the glapi symbols. This makes it impossible to build DRI drivers on systems without Mesa installed and without building the libGL from the Mesa tree first. Some automated build systems trigger this problem. This commit removes -lGL and instead adds a dummy implementation of glapi to dri_test.c This, along with Kristian's commit, should fix all known regressions due to the addition of unresolved symbol checking. --- src/mesa/drivers/dri/Makefile.template | 2 +- src/mesa/drivers/dri/common/dri_test.c | 68 ++++++++++++++++++++++++++++++++++ 2 files changed, 69 insertions(+), 1 deletion(-) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/Makefile.template b/src/mesa/drivers/dri/Makefile.template index cd800e5e017..f19cc039b22 100644 --- a/src/mesa/drivers/dri/Makefile.template +++ b/src/mesa/drivers/dri/Makefile.template @@ -54,7 +54,7 @@ $(LIBNAME): $(OBJECTS) $(MESA_MODULES) $(EXTRA_MODULES) Makefile \ $(TOP)/src/mesa/drivers/dri/Makefile.template $(TOP)/src/mesa/drivers/dri/common/dri_test.o $(MKLIB) -o $@.tmp -noprefix -linker '$(CC)' -ldflags '$(LDFLAGS)' \ $(OBJECTS) $(MESA_MODULES) $(EXTRA_MODULES) $(DRI_LIB_DEPS) - $(CC) -o $@.test $(TOP)/src/mesa/drivers/dri/common/dri_test.o $@.tmp $(DRI_LIB_DEPS) -L$(TOP)/lib -lGL + $(CC) -o $@.test $(TOP)/src/mesa/drivers/dri/common/dri_test.o $@.tmp $(DRI_LIB_DEPS) @rm -f $@.test mv -f $@.tmp $@ diff --git a/src/mesa/drivers/dri/common/dri_test.c b/src/mesa/drivers/dri/common/dri_test.c index cf59b2b7378..f55ec6d52be 100644 --- a/src/mesa/drivers/dri/common/dri_test.c +++ b/src/mesa/drivers/dri/common/dri_test.c @@ -1,8 +1,76 @@ +#include "main/glheader.h" +#include "main/compiler.h" +#include "glapi/glapi.h" + /* This is just supposed to make sure we get a reference to the driver entry symbol that the compiler doesn't optimize away */ extern char __driDriverExtensions[]; +/* provide glapi symbols */ + +#if defined(GLX_USE_TLS) + +PUBLIC __thread struct _glapi_table * _glapi_tls_Dispatch + __attribute__((tls_model("initial-exec"))); + +PUBLIC __thread void * _glapi_tls_Context + __attribute__((tls_model("initial-exec"))); + +#endif + +PUBLIC const struct _glapi_table *_glapi_Dispatch; +PUBLIC const void *_glapi_Context; + +PUBLIC void +_glapi_check_multithread(void) +{} + +PUBLIC void +_glapi_set_context(void *context) +{} + +PUBLIC void * +_glapi_get_context(void) +{ + return 0; +} + +PUBLIC void +_glapi_set_dispatch(struct _glapi_table *dispatch) +{} + +PUBLIC struct _glapi_table * +_glapi_get_dispatch(void) +{ + return 0; +} + +PUBLIC int +_glapi_add_dispatch( const char * const * function_names, + const char * parameter_signature ) +{ + return 0; +} + +PUBLIC GLint +_glapi_get_proc_offset(const char *funcName) +{ + return 0; +} + +PUBLIC _glapi_proc +_glapi_get_proc_address(const char *funcName) +{ + return 0; +} + +PUBLIC GLuint +_glapi_get_dispatch_table_size(void) +{ + return 0; +} + int main(int argc, char** argv) { void* p = __driDriverExtensions; -- cgit v1.2.3
