undetectable libraries

undetectable libraries

[Juan carlos Rebate]

good evening, I have a strange problem, I try to compile code that
uses gtk3 and sdl2 in addition to curl, the problem is that when I
invoke the gcc compiler it tells me that sdl2-devel and libcurl are
not installed, but actually yes are.
./configure --cross-prefix=x86_64-w64-mingw32- --enable-sdl
--enable-gtk --enable-curl
I'm not sure if they allow to send screenshot to show windows of the
cygwin package installer so they can see the installed packages. How
could I find the variable and add it to compile?

Did you install packages such as libcurl-devel, libgtk3-devel and
libSDL2-devel?

Check what Cygwin packages exist (allows EREs) on Cygwin site:

$ cygcheck -p libgtk[1-9].*-devel
Found 8 matches for libgtk[1-9].*-devel
libgtk1.2-devel-1.2.10-12 - libgtk1.2-devel: Gimp Toolkit GUI library (version
1.2) (installed binaries and support file

Check if Cygwin package (exact name) installed and status of installed files:

$ cygcheck -c libgtk3-devel

In the images that I have attached to this email you can see how the
packages are installed, I have always installed them this way and I
have never had failures

...that you have noticed, so far.

That's unusual, as we have probably all had issues at some point with some
package install, that we have had to remove and reinstall to fix, if we have
installed and upgraded enough packages over a long enough period of time.
Setup is normally reliable, but networks sometimes are not, and problems
occasionally occur syncing some package mirror directories, or downloading the
packages.

The question is do you have libgtk*-devel installed and what is the *current*
package status of that and the other prerequisites?

Then my next suggestion is to provide more information about your
problem. For example,

* What software are you trying to build? Do you write it by yourself?
  Or are you trying to build one that is distributed somewhere?
* It seems configure script is used. Then what outputs are displayed
  when you run it?

In addition to Yasushiro suggesstion,
the config.log is a good starting point

For what I see there is no

   mingw64-x86_64-curl

in your list so that is likely a blocking point

Would you mind revealing what code that is?

I'm pretty sure that GCC would never tell you those particular things. 
It would tell you which files it cannot find, but not which package 
they're supposed to be from.

> --enable-gtk --enable-curl

That configure call looks strange, particularly the --cross-prefix part. 
The usual way of asking configure to build for a target platform other 
than the build host would look more like this:

   ./configure --host=x86_64-w64-mingw32

The actual output from your configure run, and/or the generated 
config.log file would almost certainly be more helpful than further 
speculation about the details of cygwin setup usage.
