如何配置linaro--gcc

Question

现在我使用gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabihf和eclipse进行交叉编译。但是在构建时，我得到的错误信息如下

home/osboxes/artik5/opt/toolchains/gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabihf/bin/../lib/gcc/arm-linux-gnueabihf/5.5.0/../../../../arm-linux-gnueabihf/bin/ld: cannot find crt1.o: No such file or directory

有没有人帮我修复这个bug。我在/home/osboxes/artik5/opt/toolchains/gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/libc/usr/lib中找到crt1.o、crti.o、libpthread.so.0和libpthread_nonshared.a

Answer 1

rt1.o、crti.o、crtn.o和libc.a都是随glibc一起提供的。您需要使用--sysroot选项来告诉gcc在哪里搜索由glibc创建的二进制文件。
