Thread-topic: [CRONOLOG]: Cronolog 1.6.2 for WIndows

I think I finally have a compiled binary for Cronolog 1.6.2 for Win2K that does not depend on Cygwin1.dll. The process was a bit convoluted and so here's the instructions just in case someone wants to do the same. Hopefully this will be useful to someone else. (Note: The standard source from 1.6.2 builds fine with Cygwin but during execution, it requires Cygwin1.dll to be present in the path.) The attached files are as follows: 1. howToCompileChronolog1.6.2ForWin2K.htm - instructions on how to build, incl. errors that I have encountered and what I did to get around the error. 2. cronolog-1.6.2.windows.build.zip - a zip copy of my build directory. You can find the .exe in cronolog-1.6.2\src directory 3. a diff of cronoutils.c in html format Of importance is item (3). I had to modify 1 line in cronoutils.c when compiling. I think I am right but not sure if this is correct. It seems to compile and runs OK. To view the attached HTML files, you are going to need either IE or FireFox to view them properly) AND, as a disclaimer, this stuff hasn't been tested ! >-----Original Message----- >From: Matthew Grosso [mailto:mgrosso@xxxxxxxxxxxxx] >Sent: Thursday, September 16, 2004 9:34 AM >To: Ian Huynh >Cc: cronolog-users@xxxxxxxxxxxxxxxx >Subject: Re: [CRONOLOG]: Cronolog 1.6.2 for WIndows > > > >Ian, > >You might want to try MinGW.

Title: How to compile Chronolog 1.6.2 for Win2K

How to compile Chronolog 1.6.2 for Win2K

1 Downloading the Software

From www.mingw.org

· Install MinGW MinGW-3.1.0-1.exe

· Install MSYS MSYS-1.0.10.exe

From www.cygwin.com

· Install Cygwin and make sure that you also include the Developer Kit to get all the GCC packages.

From www.chronolog.org

· Get a copy of chronolog 1.6.2 and unzip it to a local drive

2 Compiling

· Launch MSYS

o cd to the directory where you unzipped chronolog 1.6.2

o run ./configure

o run make

· You will get this error below

gcc -DPACKAGE=\"cronolog\" -DVERSION=\"1.6.2\" -DSTDC_HEADERS=1 -DTIME_WITH_SYS_TIME=1 -DHAVE_FCNTL_H=1 -DHAVE_LIMITS_H=1 -DHAVE_UNISTD_H=1 -DHAVE_STRFTIME=1 -DHAVE_VPRINTF=1 -DHAVE_MKDIR=1 -DHAVE_MKTIME=1 -DHAVE_PUTENV=1 -I. -I. -g -O2 -c strptime.c

strptime.c:31:22: langinfo.h: No such file or directory

make[1]: *** [strptime.o] Error 1

make[1]: Leaving directory `/c/cronolog-1.6.2/lib'

make: *** [all-recursive] Error 1

· Save this snippet of code below as strptime.h inside directory lib? (Found this via googling)

#ifndef _STRPTIME_H

#define _STRPTIME_H

amplib strptime

#if TIME_WITH_SYS_TIME

# include <sys/time.h>

# include <time.h>

#else

# if HAVE_SYS_TIME_H

# include <sys/time.h>

# else

# include <time.h>

# endif

#endif

//prototypes

char *ourStrptime(const char *s, const char *format, struct tm *tm);

#endif //_STRPTIMEH

// Emacs control

// Local Variables:

// eval: (c++-mode)

· Recompiling

o Run make clean

o Run make

· Got this error below

strptime.c:31:22: langinfo.h: No such file or directory

make[1]: *** [strptime.o] Error 1

make[1]: Leaving directory `/c/cronolog-1.6.2/lib'

make: *** [all-recursive] Error 1

· Edit file lib\Makefile.in and change

DEFS = @DEFS@ -I. -I$(srcdir)

DEFS = @DEFS@ -I. -I$(srcdir) -I/c/cygnus/usr/include

NOTE: This is assuming that Cygwin was installed at at C:\Cygnus

· Reconfigure and remake

o Run ./configure

o Run make clean

o Run make

· Got this error below

make[1]: *** [cronotest] Error 1

make[1]: Leaving directory `/c/cronolog-1.6.2/src'

DEFS = @DEFS@ -I. -I$(srcdir) -I/mingw/include -I/c/cygnus/usr/include

· Reconfigure and remake

o Run ./configure

o Run make clean

o Run make

· Got this error below

cronoutils.c: In function `create_subdirs':

make[1]: *** [cronoutils.o] Error 1

make[1]: Leaving directory `/c/cronolog-1.6.2/src'

make: *** [all-recursive] Error 1

· Make a small modification in cronoutils.c around the #ifndef _WIN32 line near the mkdir function

Modified code from 1.6.2

DEBUG(("Testing directory \"%s\"\n", dirname));

if (stat(dirname, &stat_buf) < 0)

{

if (errno != ENOENT)

{

perror(dirname);

exit(2);

}

else

{

DEBUG(("Directory \"%s\" does not exist -- creating\n", dirname));

#ifndef _WIN32

if ((mkdir(dirname, DIR_MODE) < 0) && (errno != EEXIST))

#else

if ((mkdir(dirname) < 0) && (errno != EEXIST))

#endif

{

perror(dirname);

exit(2);

}

Original code from 1.6.2

DEBUG(("Testing directory \"%s\"\n", dirname));

if (stat(dirname, &stat_buf) < 0)

{

if (errno != ENOENT)

{

perror(dirname);

exit(2);

}

else

{

DEBUG(("Directory \"%s\" does not exist -- creating\n", dirname));

if ((mkdir(dirname, DIR_MODE) < 0) && (errno != EEXIST))

#ifndef _WIN32

{

#else

if ((mkdir(dirname) < 0) && (errno != EEXIST))

#endif

perror(dirname);
