sys/filio.h

sys/filio.h

[Tom Szczesny]

Hi, I am attempting to "make install" the A+ language in my Cygwin environment.

The package   aplus-fsf-4.22-4.tar.gz    is available at www.aplusdev.org

 

The configure worked fine:

   CFLAGS=-O2 CXXFLAGS=-O2 ./configure --prefix=/usr/local/aplus-fsf-4.22

 

The "make install" failed with the following message:

   AipcConnection.C:33:23: sys/filio.h: No such file or directory.

 

Any recommendations?

Sorry, but no.  On my Linux system:

% ls /usr/include/sys/filio.h
ls: cannot access /usr/include/sys/filio.h: No such file or directory

google implies that this is a Solaris header file.  Since we don't
emulate Solaris, the file does not exist on Cygwin.  If the package has
a way to build under Linux you should look into using that.

Thanks for the tip!  I was able to get the package working under Gentoo Linux.  Seems that I need to do some work on the config step (which appears to have decided that the build is being done under Solaris).   The file /usr/include/sys/filio.h  does not exist in Gentoo Linux either.

There are several places in the source code that have the following type of construction:
#if defined(_AIX) || defined(linux) || defined(__alpha) || defined(__APPLE__)extern "C" {#include <sys/ioctl.h>}#elseextern "C" {#include <sys/filio.h>}#endif
As a temporary measure, I have added a line at the beginning of each construction, stating:#define linux
While this works as a temporary fix, I need to know the name of the variable automatically defined by Cygwin so that I can do something like:#if defined(_AIX) || defined(linux) || defined(__alpha) || defined(__APPLE__) || defined(cygwin)
There is quite a long build going at the momemt, and I don't want to interrupt it to test out different possibilities.Can you either confirm that the defined variable is named "cygwin", or tell me what the actual name is?

You don't have to interrupt a build to play with the c compiler or
grep /usr/include.

As a fish teaching exercise, try this command:

gcc -xc /dev/null -dD -E

__CYGWIN__ (*2* underscores, twice)

Please read the entire thread before responding.  This question
was already answered two days ago.

Thank you's to you both:
