如何解决brew安装编译不过的问题

aerror2026-06-15 10:45

举例，如在macos 15.7下安装pkg-config会遇到以下错误:

复制代码

brew install  pkg-config

Last 15 lines from /Users/dany/Library/Logs/Homebrew/pkg-config/02.make:

解决办法，是加上--debug,如下：

复制代码

brew install --debug pkg-config

然后出错的时候，brew会提示你如下：

复制代码

make: *** [all] Error 2
/usr/local/Homebrew/Library/Homebrew/shims/shared/git --version
/usr/local/Homebrew/Library/Homebrew/shims/shared/curl --version
/usr/local/Homebrew/Library/Homebrew/ignorable.rb:29:in `block in raise'
BuildError: Failed executing: make
1. raise
2. ignore
3. backtrace
4. irb
5. shell

这个时候选择，shell.

然后 pwd

复制代码

bash-3.2$ pwd
/private/tmp/pkg-config-20260614-1862-jv8adw/pkg-config-0.29.2

然后使用如sublime之类的工具进行代码或者makefile的修改，如上面的例子，只需要加入-Wno-error=int-conversion

我们先export一个全局的变量

复制代码

bash-3.2$ export CFLAGS = "-Wno-error=int-conversion"

然后修改glib目录下的两个makefile也加入这个cflags,

复制代码

AUTOHEADER = ${SHELL} /private/tmp/pkg-config-20260614-1862-jv8adw/pkg-config-0.29.2/glib/missing autoheader
AUTOMAKE = ${SHELL} /private/tmp/pkg-config-20260614-1862-jv8adw/pkg-config-0.29.2/glib/missing automake-1.15
AWK = awk
CC = clang
CCDEPMODE = depmode=gcc3
CFLAGS = -g -O2 -Wno-error=int-conversion
CPP = clang -E

然后make && make install .

没有错之类，输入exit

复制代码

exit

然后，选择2 ignore

复制代码

bash-3.2$ exit
exit
1. raise
2. ignore
3. backtrace
4. irb
5. shell
Choose an action: 2
==> make install

然后继续，问题解决！
