Problem with qmake equals()/isEqual()

[pierrevr]

Hi,

I have a problem using the equals()/isEqual() function.
I must not have understood it well, because after seeing that it behaved differently than I thought, I inserted the following code into my .pro to test it out:
@
equals(MY_ENV_VAR,foobar) {
system(echo "OK 1")
}
equals($MY_ENV_VAR,foobar) {
system(echo "OK 2")
}
equals($$MY_ENV_VAR,foobar) {
system(echo "OK 3")
}
system(echo "var = $MY_ENV_VAR")
@

And after "export MY_ENV_VAR=foobar", I run make distclean & re-run the qmake and make files... and the result is, that all 3 tests fail, but it prints out "var = foobar" correctly.

What am I doing wrong here?

To use environment variable you have to use $$() instead of $$.
Try:
@error($$(PATH))@

Hi, p-himik;

In fact, that was my first try, after reading the manual. But I thought that it didn't work.

The problem was, though, that equals can not take an argument like: $$(...)

So this is not possible:

@
equals($$(MY_ENV_VAR), foo)
@

On the advice of peppe, I got it working by storing the value in another qmake variable, and then doing the comparison on that second variable instead of the original.

Thank you for your help,
Pierre

This is just clarification to old post about comparing environment variables within qmake (still being viewed), and also about cheking android architecture:

MY_TMP = $ $(ANDROID_NDK_TOOLCHAIN_PREFIX)
equals(MY_TMP,x86){

Notice two $$ before (AND…
