Hello, I constructed the cross compiler for arm-elf on Cygwin, referring to "Getting Started with GNU" by William Gatliff. But, I have not succeeded in construction yet. Then, I have some questions.Please answer. <Environment> Cygwin : 1.3.2 GCC : gcc-core-3.0.1 gcc-g++-3.0.1 BINUTILS : binutils-2.11.2 NEWLIB : newlib-1.9.0 HOST : Windows98 machine (i586-pc-cygwin) TARGET : ARM7(arm-elf) <Construction> STEP1 PATH was set in the file of "Cygwin.bat" as follows. ... SET PATH=/tools/arm-elf/bin:$PATH SET PATH=/bin ... and, after "Cygwin" had been started, typing later. $ export PATH=$PATH:/tools/arm-elf/bin STEP2 $ ../binutils-2.10.1/configure --target=arm-elf \ --prefix=/tools 2>&1 | tee configure.log $ make all install 2>&1 | tee make.log These succeeded. STEP3 $ cd /src/gcc-3.0.1 $ ln -s /src/newlib-1.9.0/newlib Is this link necessary? Is "libgloss" also necessary? Or, is neither necessary? STEP4 Before executing "gcc-configure", I added the definition to "/src/gcc-3.0.1/gcc/config/arm elf.h" as follows. Because not call "main()". Add: #define HAS_INIT_SECTION to beginning of elf.h file. Is this correct? Or,do not change it? STEP5 $ ../gcc-3.0.1/configure --target=arm-elf --prefix=/tools \ --without-headers --with-newlib 2>&1 | tee configure.log This succeeded. STEP6 Before executing "gcc-make", I changed "tmp/build/gcc/gcc makefile" as follows. change from: # Additional target-dependent options for compiling libgcc2.a. TARGET_LIBGCC2_CFLAGS = to: # Additional target-dependent options for compiling libgcc2.a. TARGET_LIBGCC2_CFLAGS = -Dinhibit_libc Is this correct? Or,do not change it? STEP7 $ make all-gcc install-gcc 2>&1 | tee make.log The following errors occur at "gcc-make". "arm-elf-ar:not found" Then, the error was compulsorily excluded by setting PATH of the directory with "arm-elf-ar". $ export PATH=$PATH:/tools/bin The error occurs in my PC if "gcc-make" is executed at once after "gcc-configure". Therefore, my PC has been reactivated before "gcc-make" is done. For this, is not "arm-elf-ar" found? And, how should deal? STEP8 $ ../newlib-1.9.0/configure --target=arm-elf --prefix=/tools \ 2>&1 | tee configure.log $ make all install 2>&1 | tee make.log These succeeded. STEP9 $ ../gcc-3.0.1/configure --target=arm-elf --prefix=/tools \ 2>&1 | tee configure.log $ make all install 2>&1 | tee make.log It is the same as the result of "STEP7". <Execution> When compiling by the compiler made according to procedure above, the following errors occur. libgcc.a(unwind-dw2-fde.o) : In function `size_of_encoded_value': unwind-dw2-fde.o(.text+0x5c) : undefined reference to `abort' libgcc.a(unwind-dw2-fde.o) : In function `read_encoded_value_with_base': unwind-dw2-fde.o(.text+0x1d8) : undefined reference to `abort' libgcc.a(unwind-dw2-fde.o) : In function `__register_frame': unwind-dw2-fde.o(.text+0x274) : undefined reference to `malloc' libgcc.a(unwind-dw2-fde.o) : In function `__register_frame_table': unwind-dw2-fde.o(.text+0x32c) : undefined reference to `malloc' libgcc.a(unwind-dw2-fde.o) : In function `__deregister_frame_info_bases': unwind-dw2-fde.o(.text+0x3e4) : undefined reference to `free' unwind-dw2-fde.o(.text+0x41c) : undefined reference to `abort' unwind-dw2-fde.o(.text+0x41c) : undefined reference to `abort' libgcc.a(unwind-dw2-fde.o) : In function `__deregister_frame': unwind-dw2-fde.o(.text+0x450) : undefined reference to `free' libgcc.a(unwind-dw2-fde.o) : In function `base_from_object': unwind-dw2-fde.o(.text+0x4b4) : undefined reference to `abort' libgcc.a(unwind-dw2-fde.o) : In function `get_cie_encoding': unwind-dw2-fde.o(.text+0x4e8) : undefined reference to `strlen' libgcc.a(unwind-dw2-fde.o) : In function `start_fde_sort': unwind-dw2-fde.o(.text+0x1274): undefined reference to `malloc' unwind-dw2-fde.o(.text+0x1298): undefined reference to `malloc' libgcc.a(unwind-dw2-fde.o) : In function `end_fde_sort': unwind-dw2-fde.o(.text+0x1350): undefined reference to `free' unwind-dw2-fde.o(.text+0x138c): undefined reference to `abort' unwind-dw2-fde.o(.text+0x1390): undefined reference to `abort' Please answer. ------ Want more information?
