Re: [Qbs] qbs ignores the 'manual' cpp.linkerMode behavior

[Denis Shienkov]

Hmm, how, then, about the smart *assembler* options?

For example, I have an assembler files *.s which contains both asm-code 
and c-code. It compiles before in Atmel Studio, using the "avr-gcc -x 
assembler-with-cpp" option. But, in QBS it fails, because QBS launch the 
'avr-as' instead of 'avr-gcc', and, seems the 'avr-as' have not similar 
option, so, future linking fails.

So, I use workaround:

cpp.assemblerName: cpp.compilerName

and pass to cpp.assemblerFlags propery the required compiler options.

I'm not sure if it is correct decision.

BR,
Denis

Indeed it has, and your advice is correct. This is probably a good candidate 
for our FAQ. I've created a task for it:

Hi Denis,

This issue has been asked several times.
The short answer is this: put the real linker flags without -Wl into
linkerFlags and put the other ones into driverFlags.

linkerName and linkerMode are uneeded (as far as I know).

Here is an example of how I did it:

Hope this helps,

Hi all,

I use the AVR-GCC compiler, and I need to use following command line:

"-nostartfiles -nodefaultlibs -nostdlib -Wl,-
Map="$(OutputFileName).map" -Wl,--start-group -Wl,-lm  -Wl,--end-
group -Wl,--gc-sections -mrelax -Wl,-section-start=.text=0x1f400
-Wl,-section-start=.ExtReset=0x1e000  -Wl,-section-
start=.noinit=0x801032  -mmcu=at90can128 -B "C:\Program Files
(x86)\Atmel\Studio\7.0\Packs\atmel\ATmega_DFP\1.2.132\gcc\dev\at90can
128" "

but, the qbs is too 'intelligent' and generates a wrong command line
for this options:

cpp.linkerMode: "manual"
cpp.linkerName: cpp.compilerName

cpp.linkerFlags: [
        "-nostartfiles",
        "-nodefaultlibs",
        "-nostdlib",
        "-Wl,-Map=" + product.targetName + ".map",
        "-Wl,--start-group",
        "-Wl,--end-group",
        "-Wl,--gc-sections",
        "-Wl,-section-start=.text=0x1f400",
        "-Wl,-section-start=.ExtReset=0x1e000",
        "-Wl,-section-start=.noinit=0x801032",
        "-Wc,-mmcu=" + avrdevice,
        "-B",
        "C:/Program Files
(x86)/Atmel/Studio/7.0/Packs/atmel/ATmega_DFP/1.2.132/gcc/dev/" +
avrdevice,
        "-mrelax",
    ]

resulting line looks like:

"
"C:\Program Files (x86)\Atmel\Studio\7.0\toolchain\avr8\avr8-gnu-
toolchain\bin\avr-gcc.exe" -Xlinker -nostartfiles -Xlinker
-nodefaultlibs -Xlinker -nostdlib -Xlinker "-Wl,-Map=monitorapp.map"
-Xlinker "-Wl,--start-group" -Xlinker "-Wl,--end-group" -Xlinker "-
Wl,--gc-sections" -Xlinker "-Wl,-section-start=.text=0x1f400"
-Xlinker "-Wl,-section-start=.ExtReset=0x1e000" -Xlinker "-Wl,-
section-start=.noinit=0x801032" -Xlinker "-Wc,-mmcu=at90can128"
-Xlinker -B -Xlinker "C:/Program Files
(x86)/Atmel/Studio/7.0/Packs/atmel/ATmega_DFP/1.2.132/gcc/dev/at90can
128" -Xlinker -mrelax
"
it insert еру -XLinker flags everywhere...

How to disable an 'intelligent' feature ?
