Building the entire project

[vermarajeev]

This works for me:

Not on my system

I tried putting

PRE_TARGETDEPS += dummy
MKFL = ../cryp/GNUmakefile    //cryp is a directory where the GNUmakefile is present
tst.input = MKFL
tst.commands = cd ../cryp && make
tst.CONFIG = no_link
tst.output = dummy
 
QMAKE_EXTRA_COMPILERS += tst

PRE_TARGETDEPS += dummy
MKFL = ../cryp/GNUmakefile    //cryp is a directory where the GNUmakefile is present
tst.input = MKFL
tst.commands = cd ../cryp && make
tst.CONFIG = no_link
tst.output = dummy

QMAKE_EXTRA_COMPILERS += tst

in ce.pro (project file)

I get this error

[raj@fedora4 cmbedit]# qmake ce.pro
[raj@fedora4 cmbedit]# make clean
rm -f *~ core *.core
[raj@fedora4 cmbedit]# make
make: *** No rule to make target `dummy', needed by `ce'.  Stop.

By the way I think the problem is with version.
I have qt3.3.5 on my system. Will the above soultion work for it(Qt3.3.5)???

I have attached GNUmakefile. I dont think there is any problem with it.

[vermarajeev]

Oh!! where is the attachement lost????

Never mind I think there is no need, as GNUmakefile work properly for me where I say make to the path where GNUmakefile is present...

How can I solve the problem as specified in above post???

By the way what is that dummy????
I went through Qt Assistance and found this

PRE_TARGETDEPS
All libraries that the target depends on can be listed in this variable. Some backends do not support this, these include MSVC Dsp, and ProjectBuilder .pbproj files. Generally this is support internally by these build tools, this is usefull for explicitly listing dependant static libraries.
This list will go before all builtin dependencies.

I think the above commands will work with qt3.3.5. I got to know after I went through Qt assistance. I'm just trying out something. Let's see if it works....

I used this and it runs the makefile

PRE_TARGETDEPS += libcryp.a
MKFL = cryptoPP/GNUmakefile
tst.input = MKFL
tst.commands = cd cryptoPP/ && make
tst.CONFIG = no_link
tst.output = libcryp.a
QMAKE_EXTRA_UNIX_COMPILERS += tst

PRE_TARGETDEPS += libcryp.a
MKFL = cryptoPP/GNUmakefile
tst.input = MKFL
tst.commands = cd cryptoPP/ && make
tst.CONFIG = no_link
tst.output = libcryp.a
QMAKE_EXTRA_UNIX_COMPILERS += tst

It creates the static library libcryp.a. Evenrything goes on fine
but at last this error occurs

What is wrong here now???

I had these kind of problems, when I had an "empty" pro file. i.e. when I had no targets/sources in the file itself.

Qmake tries to compile "No Source File", and then tries to link it. Of course, when you do not have no source, you did not define a main function...which your linker complains about.

Add your real project infos to the pro file and the problem should vanish...

I missed that the problem regards Qt3... It won't work as qmake3 uses different variable names. You should consult the docs to see if you can convert the solution to Qt3.

I think the problem is with this statement
tst.CONFIG = no_link

I tried looking for it in Qt3.3.5 but couldnt find. I googled to find this

Not linking with the output of QMAKE_EXTRA_UNIX_COMPILERS
qmake assumes that the output of the extra compilers is destined to be linked into the final library or application. If this isn't the case, then you need to do something to stop it.
 
If "mycompiler" is the name of your compiler compound variable, then if you have a member .CONFIG set to no_link, then the output won't get linked. Example.
 
mycompiler.output = ${QMAKE_FILE_BASE}.out
mycompiler.input = MYCOMPILER_INPUT_FILES
mycompiler.commands = foo ${QMAKE_FILE_NAME}
mycompiler.CONFIG = no_link
QMAKE_EXTRA_UNIX_COMPILERS += my_compiler 
 
Examples when you might want to do this are for things like generating documentation.

This is related to Qt4.. What should I replace with no_link in Qt3.3.5 to resolve the above problem.

Hi camel I tried what you have suggested but I get the same error as shown in above post.
Is there any way out???
