I would like to cross compile a simple program that uses libncurses on my x86_64. Target system is MIPS.

My crosstool-ng-1.20 build went fine (with sample mips-unknown-elf)

However, a simple hello world ends badly.

#include <stdio.h>       

int main(void)           
{                        
    printf("OH HAI.\n"); 
    return 0;            
}

--

x86host:~/toolchain$ mips-unknown-elf-gcc -o hello hello.c

hello.c:1:19: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
                   ^
compilation terminated.

I'm clearly doing something terribly wrong here, but where do i start?

[Edit]

Thank you markgz. Codesourcery is exactly what i needed.

mips-linux-gnu-gcc.exe -static -o helloStatic hello.c

Proof of concept complete. Now off to compile my ncurses program.

您可能需要构建 mips-linux-elf-gcc。您确定您的 MIPS 目标系统配置为大端序吗？

无论如何，您可以通过从这里下载免费的 Mentor/Codesourcery MIPS gnu/gcc 交叉编译工具链来避免所有这些问题。此工具链适用于 Windows 和 Linux。

然后，我从 /usr/include/ 复制了一些标题以使它们消失：

root@x86host:~/ninvaders-0.1.1# mv nInvaders nInvaders_IOSXE_MIPS

对于未来的谷歌人，Makefile 是：

CC=mips-linux-gnu-gcc -static
CFLAGS=-O -Wall
LIBS=-lncurses
LDFLAGS=-L /root/ncurses-5.9-20141101/lib

CFILES=globals.c view.c aliens.c ufo.c player.c nInvaders.c
HFILES=globals.h view.h aliens.h ufo.h player.h nInvaders.h
OFILES=globals.o view.o aliens.o ufo.o player.o nInvaders.o
all:            nInvaders

nInvaders:      $(OFILES) $(HFILES)
                $(CC) $(LDFLAGS) -o$@ $(OFILES) $(LIBS)

.c.o:
                $(CC) -c  -I. $(CFLAGS) $(OPTIONS) $<
clean:
                rm -f nInvaders $(OFILES)

最终结果：

root@x86host:~/ninvaders-0.1.1# file nInvaders_IOSXE_MIPS
nInvaders_IOSXE_MIPS: ELF 32-bit MSB  executable, MIPS,
