I am trying to build libusb as shared library as follows.
Following are two steps. 1. Configure 2. Make.
I pass "--enable-shared" to configure script assuming it will generate the shared .so file
Configure

But I cant find libusb-1.0.so
The .so file is built in libusb/.libs/
Its not very obvious by looking at the build logs though.

I tried to install a library (RNNoise) on Cygwin with ./autogen.s - ./configure - make - make install.
Below is the result I got:

It seems that everything works well. However, I couldn't find the library (rnnoise). I searched through pip list and imp.find_module('rnnoise').
Is the library installed successfully? How do I know the name or path of the library?

How do I fix my configure.ac so that checking of dependencies is done only once?
The second invocation of configure has been made when doing make -j4 in Makefile by the following rule
$(top_builddir)/config.status: $(top_srcdir)/configure $(CONFIG_STATUS_DEPENDENCIES)
$(SHELL) ./config.status --recheck
It could be a case that the configure is change leading to the make trigger recheck. You need to check content of configure script before/after you issue the ./configure command
In the other hand, there should something defined in CONFIG_STATUS_DEPENDENCIES
Please consider the following project.
configure.ac:
AC_PREREQ([2.69])
AC_INIT([dummy-project], [0.0.1])
AM_INIT_AUTOMAKE([foreign])
LT_INIT([disable-static])
AC_PROG_CXX
AC_CONFIG_FILES([Makefile])
AC_OUTPUT
Makefile.am:
noinst_LTLIBRARIES=something.la
something_la_SOURCES=source.cpp
something_la_LDFLAGS=-module
source.cpp is just an empty file.
When I run:
/tmp/scratch$ autoreconf -i
libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac,
libtoolize: and rerunning libtoolize and aclocal.
libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

For some reason, it creates .libs/something.a (pic compiled for static linking to another so), but not something.so like I need it to.
I'm doing something wrong here, but I don't know what.
There are two parts to the answer. One is on the automake level, and the other is on the libtool level.
On the automake level, the moment a library is defined under the noinst_LTLIBRARIES rule, it is assumed to be a "convenience" library. Such a library is used internally by your build system, not intended to be installed at runtime.
On the libtool level, since a convenience library will not be installed, there is no need to build a shared object version of it. The build for shared object libtool does is to compile a .o file (static linked) with -fpic so that it can be statically linked into another shared object.
The mechanism by which libtool knows this is a convenience library is by seeing whether an rpath was provided. If no rpath was provided, the output is assumed to be a convenience library, and no shared object is generated.
Whenever I run the configure script of GNU-Autotools by running the ./configure command. It consume all my RAM(4GB) very fast immediately during 5 second then hang my computer. I use Linux system and I test this problem with different GNU source packages and the result is same. You can see an example of running configure below:
I break the process by CTRL+C when the process reach to "checking for BSD- or MS-compatible name lister (nm)...".

After all checking, Here Memory Finished and I break the Process by CTRL+C to Rescue My Computer.
First I reinstalled the binutils to solve the problem with nm but nothing didn't changed then I removed binutils and it's dependencies and I install it again and now everything works perfect.
I didn't find what was happened about nm but I just found that was the problem during configure process.
I hope this answer help other people too.
There seems to be a problem compiling freetype2 with MinGW and MSYS
My attempts on a clean copy of the freetype source, and an unadulterated MinGW and MSYS give:
Andrew#MCARDLE-PC ~/documents/code
$ cd freetype-2.3.11
Andrew#MCARDLE-PC ~/documents/code/freetype-2.3.11
$ ./configure
FreeType build system -- automatic system detection
The following settings are used:
platform unix
compiler cc
configuration directory ./builds/unix
configuration rules ./builds/unix/unix.mk
If this does not correspond to your system or settings please remove the file
`config.mk' from this directory then read the INSTALL file for help.
Otherwise, simply type `c:/code/mingw/bin/make' again to build the library,
or `c:/code/mingw/bin/make refdoc' to build the API reference (the latter needs
python).

To my mind the two problems appear to be sed not recognising 'C', and libtool not being found.
The solution is to delete C:\mingw\bin\sed.exe so the MSYS sed will get used instead.
In your msys Environment, path/to/msys/installation/bin is mounted to /bin and MinGW is usually mounted to /mingw.
The problem is due to sed.exe coming from either /mingw/bin (or GnuWin32's bin or Git's bin, etc... if you have those installed), and not from /bin, as /bin is being included after all these in your msys Environment path.
The solution is to start your msys environment with the argument MSYS so that /bin comes before /mingw/bin (and possibly the rest as mentioned above) in your msys Environment's PATH, and hence sed.exe from /bin be used.
From your command prompt, assuming your Windows path contains /path/to/msys/installation/, use
$> msys.bat MSYS
instead of
$> msys.bat
to launch msys.
To test if everything is in order, echo $PATH under msys to see the Environment's PATH is correct.
