Linux Ubuntu使用make编译失败，提示错误127和GCC权限不够

Posted 2023-05-15

简单的c语言程序，Makefile文件内容如下：
# Toolchain
TOOLCHAIN_TOP?=/opt/toolchain_mp1800
PATH:=$(PATH):$(TOOLCHAIN_TOP)/bin
export PATH
# Cross compiler
CROSS_COMPILE=mipsel-linux-uclibc-
CC=$(CROSS_COMPILE)gcc
STRIP=$(CROSS_COMPILE)strip
#
CFLAGS ?=-Os -pipe -mips32 -mtune=mips32 -funit-at-a-time -fhonour-copts -fPIC
LDFLAGS?=
LDLIBS ?=
all: hello
hello.gdb: hello.o
$(CC) $(LDFLAGS) -o $@ $^ $(LDLIBS)
hello: hello.gdb
@cp -f $^ $@
$(STRIP) -s $@
clean:
rm -f *.o hello *.gdb

执行结果如下：
root@ubuntu:~/hello# make
mipsel-linux-uclibc-gcc -Os -pipe -mips32 -mtune=mips32 -funit-at-a-time -fhonour-copts -fPIC -c -o hello.o hello.c
make: execvp: mipsel-linux-uclibc-gcc: 权限不够
make: *** [hello.o] 错误 127
root@ubuntu:~/hello#

求解!
赋予777权限后，运行，继续报错，如下：
cc1: error: /opt/toolchain_mp1800/bin/../lib/gcc/mipsel-linux-uclibc/4.1.2/../../../../mipsel-linux-uclibc/sys-include: not a directory
mipsel-linux-uclibc-gcc: error trying to exec '/opt/toolchain_mp1800/bin/../lib/gcc/mipsel-linux-uclibc/4.1.2/../../../../mipsel-linux-uclibc/bin/as': execv: Exec format error
make: *** [hello.o] 错误 1

参考技术A mips工具链有问题，file mipsel-linux-uclibc-gcc ，看看它是在多少位的系统上用的？ 参考技术B 找到这个文件：mipsel-linux-uclibc-gcc 看看它有没有设置可执行权限。。。

不如你写一个简单的程序，把程序的代码、编译输出全部发上来，看看有没有人能帮你，本回答被提问者采纳 参考技术C 试试root下编译吧，如果还不行，那就是你这个编译器有问题

ubuntu 下用于 C++ 编译的 OpenCV 2.4.13 失败

【问题描述】：

我正在尝试在 ubuntu 上为 C++ 安装 openCV。我正在使用 this document 。但编译步骤失败。 make的日志如下：

$make

你能帮我解决这个编译问题吗？

【问题讨论】：

QtOpenGL 已安装

【参考方案1】：

我通过运行避免了编译错误：

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_QT=ON -D WITH_OPENGL=ON ..

代替：

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

【讨论】：

我还安装了这两个包：libqt5opengl5 libqt5opengl5-dev。 （参考：***.com/questions/31538560/…）
