POMakefile: Why can't I see compilation output?
text
Body
copied!<p>I have a master <code>Makefile</code> that calls submakefiles inside directories. Those submakefiles are generated by autotools starting from <code>Makefile.am</code> and <code>configure.ac</code> files.</p> <p>The first target of the entire project is a shared library, while the others are executables that link against it (so there is a dependency in the main <code>Makefile</code>).</p> <p>The problem is that I can only see the compilation output of the shared library, while the other projects are just printing warnings and errors (just <code>stderr</code> text, I believe).</p> <p>I can't understand what is causing this behaviour since all the projects are called from the very same rule in the master <code>Makefile</code> and all the submakefiles are autogenerated from very seemed configuration files.</p> <p>The snippet of master <code>Makefile</code> that compiles all the targets looks like this:</p> <pre><code>SUBDIRS = libMylib app1 app2 app3 $(SUBDIRS): $(ECHO) "-> Building $@" $(MAKE) -C $@ $(ECHO) "-> Build of $@ finished." </code></pre> <p>The output of "libMylib" is like:</p> <pre><code>-> Building libMylib libtool: compile: ppc-linux-gcc -DHAVE_CONFIG_H -I. -I/opt/ELDK/ppc_8xx/usr/include/ -I/opt/ELDK/ppc_8xx/include/ -Wall -std=gnu99 -O2 -MT libMylibF1.lo -MD -MP -MF .deps/libMylibF1.Tpo -c libMylibF1.c -fPIC -DPIC -o .libs/libMylibF1.o ... libtool: link: ppc-linux-gcc -shared -fPIC -DPIC .libs/libMylibF1.o .libs/libMylibF2.o .libs/libMylibF3.o -Wl,-rpath -Wl,/opt/ELDK/ppc_8xx/lib -Wl,-rpath -Wl,/opt/ELDK/ppc_8xx/lib -lz -lpthread -O2 -Wl,-soname -Wl,libMylib.so.0 -o .libs/libMylib.so.0.0.0 libtool: link: (cd ".libs" && rm -f "libMylib.so.0" && ln -s "libMylib.so.0.0.0" "libawmg.so.0") libtool: link: (cd ".libs" && rm -f "libMylib.so" && ln -s "libMylib.so.0.0.0" "libMylib.so") libtool: link: ( cd ".libs" && rm -f "libMylib.la" && ln -s "../libMylib.la" "libMylib.la" ) -> Build of libAwmg finished. </code></pre> <p>While the output of any "appN" is:</p> <pre><code>-> Building app1 app1F1.c: In function `app1F1Func1': app1F1.c:161: warning: unused variable `varA' app1F2.c:85: warning: `app1F2FuncX' defined but not used -> Build of app1 finished. </code></pre> <p>Could anyone please help me?</p> <hr> <p>EDIT:</p> <p>I found out that I was able to see the compile stuff in "libMylib" because it is "libtoolized". If I "libtoolize" another project, I can see the linker part of the output (<code>libtool: link:...</code>).</p> <p>So, considering that <code>make</code> calls a shell (<code>sh</code>) for each line in the rule, that $(MAKE) equals to just "make" and, by default, <code>make</code> is verbose, why do the submake is not printing its output to stdout?</p> <p>Which flags may be passed to it so that this happens?</p>
