Dollar signs in QMAKE_POST_LINK

c.cardona

I have been trying to run a post link command by using the QMAKE_POST_LINK variable, but to no avail. My command contains dollar signs and there is no way to avoid using them; somehow, these are never shown when the command gets printed after building, and the command is never run successfully.

I have tried escaping the dollar sign with $${LITERAL_DOLLAR} (see this, probably outdated), with just $$, with \$, by declaring a DOLLAR=$ variable and then using it within the command... Nothing works.

Any ideas?

Hi and welcome to devnet,

Which version of Qt are you using ?
On which OS ?
Can you provide a minimal .pro file that reproduces that ?

@SGaist Hi, sorry for the little information I provided, it's my first time posting.

I am using MacOS 12.5.1 and Qt 5.15.9.

Here is an example .pro file:

TARGET = MyApp
TEMPLATE = app

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.12
SOURCES += src/main.cpp

QMAKE_POST_LINK = echo "This is shown"
QMAKE_POST_LINK += && cat $(echo "~/thisWillNotShow.txt")

The first line (echo "This is shown") will execute, but the second will only execute cat and stop as soon as it sees the $. The QMAKE_POST_LINK command that qmake shows it is executing is indeed just echo This is shown && cat.

I don't have an answer yet with regard to the dollar issue but in the meantime, would using backticks around the command be a workaround you can use ?
