QMake $${LITERAL_DOLLAR}0 not expanded to command line at compile - Qt Creator, MacOS

trevorS

I am trying to pass $0 to the command line without success. While the qmake message function properly expands LITERAL_DOLLAR, it is not expanded on the command line at compile.

You can see in the qmake code and compile output below that both the LITERAL_DOLLAR and proceeding 0 are omitted from the awk command.

[QMake Code]

MY_DIR = MyDir=/Library/mydir

message("COMMAND awk 'NR==2 {$${LITERAL_DOLLAR}0=\"$${MY_DIR}\"} 1' myrc.sample > .myrc")

myrcupdate.target   = .myrc
myrcupdate.depends  = myrcupdateMessage
myrcupdate.commands = awk \'NR==2 {$${LITERAL_DOLLAR}0=\"$${MY_DIR}\"} 1\' myrc.sample > .myrc

myrcupdateMessage.commands = @echo Updating myrc entry $${MY_DIR}

QMAKE_EXTRA_TARGETS += myrcupdate myrcupdateMessage
PRE_TARGETDEPS      += .myrc

[Compile Output]

The kit Desktop Qt 5.7.1 clang 64bit static has configuration issues which might be the root cause for this problem.

Is this qmake behaviour intentional ?

While I'm still not successful to expand $${LITERAL_DOLLAR}0 to the command line at compile, I did resolve the generated compile error by changing from awk to sed.

[Work around]

Change...

myrcupdate.commands = awk \'NR==2 {$${LITERAL_DOLLAR}0=\"$${MY_DIR}\"} 1\' myrc.sample > .myrc

to...

myrcupdate.commands = sed -i \'\' \'2s%.*%$${MY_DIR}%\'  .myrc
