Monit Compilation Errors

Monit Compilation Errors

[Kizito Porta Balanyà]

Hello all,

I'm trying to compile the last version of MONIT and I get some errors that
I can not solve.

Basically I get errors like: expected identifier or ‘(’ before numeric
constant, but reviewing the code I don't see any wrong, beside that the
sources compile correctly with Linux, AIX, etc ...

Can you help me? Do you have any clue?

I show you the errors obtained:

Thanks in advance, and have a new good year,

I tried to reproduce the problem, but I think you must be using 
different sources than what I found.  I downloaded monit-5.25.1.tar.gz 
from https://mmonit.com/monit/ and found that I couldn't configure it:

$ ./bootstrap
[...]

$ ./configure --without-pam
[...]
configure: error: Architecture not supported: CYGWIN_NT-10.0-WOW
configure: error: ./configure failed for libmonit

Also, the line numbers in my sources differ from those in your error 
messages.  Could you say where you got your sources and how you tried to 
build?

Ken

Re: Monit Compilation Errors

[BGINFO4X]

Hello again,

Well,your are right, I modified the sources to port monit to cygwin, as I
did correctly in version 5.10.

Below you will find a quick how-to (and at the end the required diff files).

##############################################################
CYGWIN PACKGAGING
##############################################################

0- Install Cygwin via setup-x86_64 or setup-x86 from https://www.cygwin.com

1- The following packages are required from the Cygwin:

Devel Tree:
make, autoconf,automake,gcc-core,bison,libtool,flex, cygwin32-zlib,
zlib-devel

Libs Tree:
libcrypt-devel


    Select also all the required dependecies when installing

##############################################################
MONIT DOWNLOAD
##############################################################

2- For better success, start cygwin.bat or cygwin Terminal with
Administration Elevation Privileges "Run as Administrator":

3- Download monit source from https://mmonit.com/monit/ and copy it to your
"cywin forlder"/tmp:

$ cd /tmp
$ tar xvfz monit-5.25.1.tar.gz
$ cd monit-5.25.1


##############################################################
CREATE SYSTEM DEPENDENCIES FILES
##############################################################

Copy the Minimal System Dependencies from sysdep_UNKNOWN to the cygwin
architecture:

cp file /src/device/sysdep_UNKNOWN.c /src/device/sysdep_CYGWIN.c
cp file /src/process/sysdep_UNKNOWN.c /src/process/sysdep_CYGWIN.c


##############################################################
ADAPT CONIFUGRE.AC TO CYGWIN in # Architecture/OS part of code

    CFLAGS="$CFLAGS -D _REENTRANT"
### LDFLAGS="$LDFLAGS -lcrypt"
###    CFLAGS="-E $CFLAGS -D _REENTRANT"

For libmonit configure.ac:

In monit.h add:

#ifdef CYGWIN

#ifndef ICMP_ECHO
#define ICMP_ECHO 8

#ifndef ICMP_ECHOREPLY

#endif

#endif

##############################################################
ADAPT NET.C

In net.c modify icmp_echo function:

    return -1;
}
#else

        ASSERT(hostname);

From https://gcc.gnu.org/onlinedocs/cpp/System-specific-Predefined-Macros.html

"historically system-specific macros have had names with no special
prefix; for instance, it is common to find unix defined on Unix systems.
[...] When the -ansi option, or any -std option that requests strict
conformance, is given to the compiler, all the system-specific predefined
macros outside the reserved namespace are suppressed."


You can see the predefined macros with `cpp -dD /dev/null'.

$ cpp -dD /dev/null
# 1 "/dev/null"
# 1 "<built-in>"
[...]
#define __unix__ 1
#define __unix 1
#define __declspec(x) __attribute__((x))
#define __DECIMAL_BID_FORMAT__ 1
# 1 "<command-line>"
#define unix 1                     <-- this is your problem
# 1 "/dev/null"


With -ansi:

$ cpp -ansi -dD /dev/null
# 1 "/dev/null"
# 1 "<built-in>"
[...]
#define __unix__ 1
#define __unix 1
#define __declspec(x) __attribute__((x))
#define __DECIMAL_BID_FORMAT__ 1
# 1 "<command-line>"
# 1 "/dev/null"


$ cpp --version
cpp (GCC) 6.4.0


You can undefine the unix macro or rename the unix struct.

Looks like -std=c99 without -ansi does not suppress those symbols so add -ansi
to CFLAGS, use equivalent configure options, or autoconf/automake changes.

I'd go with the minimally intrusive `CFLAGS=-Uunix'. -ansi can have undesirable
side effects.

Re: Monit Compilation Errors

[BGINFO4X]

Hello again,

Yes, you are right, --ansi have undesirable effects like:

In file included from src/net.h:30:0,
                 from src/p.y:120:
src/monit.h:124:1: error: C++ style comments are not allowed in ISO C90
 //FIXME: we can export this type in libmonit
 ^
etc ...

Finally, fter switching to the 32bits cygwin version (-m32 in cygwin64
generated more errors), and modifying Lync.c , monit has been compiled
again for this version.

$ ./monit.exe --version
This is Monit version 5.25.1
Built without ssl, without ipv6, with compression, without pam and without
large                                                        files
Copyright (C) 2001-2017 Tildeslash Ltd. All Rights Reserved.

And the http service works:

http://localhost:2812
user: admin, pwd: monit
Monit Service Manager Running

What are the next steps? Try to compile for the 64bits version? Both
packages are required or only one? In that case, the 64bits cygwin
installer can install the 32 bits monit version?

Thanks a lot for your time.
Regards.

Congrats. (-m32 is not supported on cygwin, don't use it.)

You can't mix 32 and 64-bit programs. If you want to use it in 64-bit
cygwin, you should recompile it.

Which is the best way to compile a program for both platforms (32-64 bits)
to release a cygwin package?

Thanks.

Do the people (port owners) compile all the ports manually each time?

cygport allows to automatize all the process
of compilation/installation/packing

Depending on how cleanly the sources and build system are set up you
could cross-compile one or the other or even both (from GNU/Linux), but
if you want to run the test suites you should simply have both a 32bit
and 64bit Cygwin installed and use those.  Unless you want to devote two
machines, that implies a native 64bit Windows and the 32bit installation
using WoW64.

I use a dedicated Win8.1 build box that doesn't see any other use and I
have another one with Win10 for the occasional test.  If you'd rather
use your main machine, it's a good idea to either have separate
development installations of Cygwin for the builds or run them in a
clean VM.

Achim.

Automate what, the Cygwin install?  Yes, BTDT.

> Do the people (port owners) compile all the ports manually each time?

Sort of, if you have many packages there will be some amount of
scripting going on or you'll go insane.  Full build automation with a
full blown CI?  I might do that at work when I get some time and
computing power to play with.  Unfortunately there are not a lot of
options when you consider building in the clouds, unless you already
have a venue tat gives you something with Windows installed.
