nim-lang / Nim

Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).

Regression: vcc compiler options can't be configured in cfg or nims files #11000

Closed cooldome closed 5 years ago

cooldome commented 5 years ago

set vcc options in cfg or nimscript files are now ignored, effectively they are always overriden by what is specifed in nim/config/nim.cfg.

Example add to project.cfg a line:

vcc.options.always = "/INCORRECT"

it will not appear the command line arguments anymore.

Regression caused by commit df3d08b58b172dae6fe1f2ecb72db288166d211d

Options in cfg or nimscript files loaded after nim/config/nim.cfg can overwrite options in nim/config/nim.cfg, but nim/config/nim.cfg cannot overwrite these options. Before commit df3d08b, $cpu.$os.vcc.* options are not set in nim/config/nim.cfg and vcc.* options are always used in both native compile and cross compile. So you can set vcc.options.always = "/INCORRECT" in your project.cfg so that it appears in the command line when you set --cpu:i386. But that caused issue #10387. After commit df3d08b, $cpu.$os.vcc.* options are set in nim/config/nim.cfg and vcc.* options are used in only native compile not in cross compile. If you are using x86_64 Nim and set --cpu:i386 option to do cross compile, your project.cfg need to use i386.windows.vcc.* options instead of vcc.* options.

For example:

i386.windows.vcc.options.always = "--platform:x86 /nologo /someoption"

I reverted "nim/config/nim.cfg" to commit df3d08b and tried to native compile and cross compile to i386 cpu with latest devel Nim on Windows 8.1. vcc.options.always = "/incorrect" set in nim.cfg affects native compile but ignored in cross compile.

git checkout df3d08b config\nim.cfg

Both test.nim and nim.cfg are in same directory.

test.nim:

echo "foo"

nim.cfg:

vcc.options.always = "/incorrect"
