[英]Using AM_INIT_AUTOMAKE parameters and configure script command line parameters
Is it possible to use both command line parameters to the configure script, ala: 是否可以将两个命令行参数都用于配置脚本ala:
../configure CXXFLAGS=-O0 -g -foo -bar -bat
../configure CXXFLAGS = -O0 -g -foo -bar -bat
while simultaneously keeping any options that are passed to AM_INIT_AUTOMAKE in the configure.ac file? 同时保留在configure.ac文件中传递给AM_INIT_AUTOMAKE的任何选项? eg:
例如:
AM_INIT_AUTOMAKE([-Wall -Werror])
AM_INIT_AUTOMAKE([-Wall -Werror])
My desired result is that ALL of the above flags are passed along, eg: 我期望的结果是上述所有标志均被传递,例如:
-O0 -g -foo -bar -bat -Wall -Werror
-O0 -g -foo -bar -bat -Wall -Werror
It appears that specifying CXXFLAGS on the command line either ingores or overwrites what is passed into AM_INIT_AUTOMAKE. 似乎在命令行上指定CXXFLAGS会填满或覆盖传递给AM_INIT_AUTOMAKE的内容。 If anyone knows of a way to do the union of the two sets, that would be extremely helpful.
如果有人知道两种方法的结合方法,那将非常有帮助。 Thx!
谢谢!
The -W
warning categories options have nothing to do with C[XX]FLAGS
. -W
警告类别选项与C[XX]FLAGS
无关。 These are command line arguments used when invoking automake. 这些是调用自动制作时使用的命令行参数。
Conversely, the AM_INIT_AUTOMAKE
options like -Wall
don't affect the compiler flags. 相反,
-Wall
之类的AM_INIT_AUTOMAKE
选项不会影响编译器标志。 It's just the decision to use these switch names that is resulting in the confusion. 只是使用这些开关名称的决定才导致混乱。 They have a similar meaning, eg,
-Werror
will treat automake warnings as errors, but are totally unrelated. 它们具有相似的含义,例如,
-Werror
将把自动制作警告视为错误,但完全不相关。
In short, you have to pass -Wall
, etc., in C[XX]FLAGS
to influence the compiler. 简而言之,您必须在
C[XX]FLAGS
传递-Wall
等,以影响编译器。 And add -Wall
to AM_INIT_AUTOMAKE
to enable all warning categories when automake is invoked. 并将
-Wall
添加到AM_INIT_AUTOMAKE
以在调用自动制作功能时启用所有警告类别。
