Re: Problem compiling 4gl/cgi when I don't have esql
This was covered in a previous posting from me in December 1995. I attach my records on the subject...

I followed the instructions and read the Informix CGI.FAQ. We only have the Informix-4GL/RDS and do not have esql/c. The makefile that comes with the package appears to expect esql regardless. There are 6 .ec files that my system cannot handle (obviously?). =========================================================================== Date: Thu Dec 21 18:12:22 1995 From: johnl (Jonathan Leffler) Subject: Re: cgi_rds problems w/o esql/c I'll let you into a minuscule secret -- you don't really need ESQL/C after all, but you do have to fix the source code, file names and the makefile for the build to work without ESQL/C. As far as I can see, the files in question are: cgiprintblob.ec icgiencode.ec icgimimetype.ec icgidecode.ec icgigetvalue.ec icgiprintblob.ec None of these contain executable ESQL/C statements. They are named as ESQL/C files to simplify compilation; the esql script provides the correct -I directives. To fix the problem, rename these files as .c files. Edit them, replacing '$include xyz;' by '#include "xyz.h"'. Remove stray $ signs from variable declarations. Edit the makefile lib4glcgi.mak: change the suffixes in the macros CGIU_ECFILES and IECFILES from ".ec" to ".c". Change the macro for UEOBJ to use ".c" in place of ".ec". Change the macros for ICECFILES and UCECFILES so that the RHS of the macro is empty; this means that your carefully produced .c files don't get cleaned up for you. I haven't done the necessary testing to be certain that that's all you have to do, but there's a reasonable chance. It assumes that you have, or can locate, copies of the sqltypes.h and locator.h headers -- if you can't, you are completely stuck.

The code in i4glsetenv.c pops 32kB of characters (mostly blanks) and tries to set that as the environment variable. Not a good idea. The code in i4glsetenv.c should be like the code in icgisetenv.c, and should use cgi_trim() to strip the trailing blanks. Additionally, it is easily arguable that the maximum length of the envarg variable should be triggered off ARG_MAX defined in <limits.h>, defaulting to _POSIX_ARG_MAX (which is 4096) if it is not available. Meaningful environment variables should be much shorter than that! This would apply to the code in both icgisetenv.c and i4glsetenv.c. Actually, I'm not even clear why there is so much duplicated code... If your version of I4GL is recent enough, there is a popstring() function in it which automatically strips off the trailing blanks and it should be used in preference to popquote(). Etc...
