hello all: I had built a cross compiler host=mingw32, target=arm-pe and now i have a problem of create shared dll.(binutils-2.13-20020903-1-src.tar.gz,gcc-3.2-20020817-1.src.tar.gz from mingw) 1. test.def ------------------------ LIBRARY test.dll EXPORTS _TestFunc ---------------------------- building dlltool -d test.def -e test.exp -C -D test.dll -l test.lib -f -mcpu=arm7dmi -f -march=armv4 2. test.c ------------------------ int _DllMainCRTStartup(int pPcb, int op, void* arg3) {return 1;} void TestFunc() {return;} ------------------------ building gcc -O0 -c -fno-exceptions -fno-rtti -fms-extensions -w -falign-functions=4 -mcpu=arm7dmi -march=armv4 test.c 3. using ld to create dll ld --dll --subsystem console --entry __DllMainCRTStartup -Map test.map --image-base 0x10000000 -o test.dll test.exp test.o But this dll doesn't have relocation table objdump -x test.dll test.dll: file format pei-arm-little test.dll architecture: armv4, flags 0x00000132: EXEC_P, HAS_SYMS, HAS_LOCALS, D_PAGED start address 0x10001000 Characteristics 0x6607 relocations stripped // no relocations information executable line numbers stripped debugging information removed DLL [snip] I could do the same job with mingw32 gcc for win32, just two differences: a) at step 1,omit the leading underscore for TestFunc in def file; b) at step 3, add -shared option for ld.exe and this dll has relocation information. Document said that -shared option of ld is" Create a shared library. This is currently only supported on ELF, XCOFF and SunOS platforms...." , i am not sure whether it support arm-pe configuration. when give -shared option to my arm-pe gcc, ld reports: Cannot export TestFunc: symbol not found Cannot export _DllMainCRTStartup: symbol not found Any ideas about this situation?
