linux - 永久设置 make 使用的线程数

Question

当我想在 Linux 中使用 make 命令进行编译时，我总是使用 -j9 运行它来设置要使用的线程数。有没有办法将其永久设置在环境路径或.bashrc文件或任何其他方式中？

Answer 1

您可以设置带有额外标志的 GNUMAKEFLAGS 环境变量以传递给 GNU make，例如:

export GNUMAKEFLAGS=-j9

在 shell 启动脚本中。

GNUMAKEFLAGS

Other flags parsed by make. You can set this in the environment or a makefile to set make command-line flags. GNU make never sets this variable itself. This variable is only needed if you’d like to set GNU make-specific flags in a POSIX-compliant makefile. This variable will be seen by GNU make and ignored by other make implementations. It’s not needed if you only use GNU make; just use MAKEFLAGS directly.
