Known issues and workarounds
____________________________________
A. Installing 4GL and CSDK into same folder can result in issues with
4GL at runtime, check the machine notes for platform specific
issues and CSDK versions.
Workaround :
It is highly recommended that 4GL and CSDK/IDS be installed into
separate folders.
B. The 4GL version 7.50.xC3 web services functionality is not compatible
with HCL Informix Dynamic Server version 7.31.
C. In HCL Informix 4GL version 7.50.HC1 and later, the compiler "c4gl" returns
the following error when trying to compile any 4GL program:
/usr/ccs/bin/ld: Can't find library: "cur_colr"
Workaround:
In HP-UX 11.31, create a symbolic link for libcur_colr.1 under
$INFORMIXDIR/lib/esql and $INFORMIXDIR/lib/tools directories
which points to /usr/lib/libcurses.sl.
For example:
ln -s /usr/lib/libcurses.sl $INFORMIXDIR/lib/esql/libcur_colr.1
ln -s /usr/lib/libcurses.sl $INFORMIXDIR/lib/tools/libcur_colr.1
D. When using the Development version of 4GL 7.50.xC2 and later to deploy
the 4GL function as a web service, if any of the files or
directories in the directory pointed to by the $TMPDIR in the
configuration file do not have permissions, the PERL script
returns this error:
This is an issue with the application org.apache.axis2.wsdl.WSDL2C
used by this deployment tool.
Exception in thread "main" org.apache.axis2.wsdl.codegen.

This error occurs frequently when /tmp is the designated $TMPDIR
because /tmp is shared by all the users and all the processes.
$TMPDIR should be used by one user only and should not contain any files
or directories that do not have permissions.
Workaround:
Option 1: Create a new directory and designate it as a $TMPDIR. For example,
mkdir /tmp/w4gl_<loginid>
In the example above, <loginid> is the user's login id into the
operating system.
Option 2: Remove all the files or directories from $TMPDIR for which the
user does not have privileges.
E. Statements inside SQL blocks duplicates the first character of a string that
starts with an hypen.
For Example :
MAIN
SQL
UPDATE tab
SET col1= col1* -2 WHERE key="key"
END SQL
Both 4GL pcode compiler and C compiler generate wrong code for the above SQL statement,
for given example above generated 4ec files will have following statement
update tab set col1 = col1 * - 22 WHERE key = "key"
Correct translation should be 'col1 * - 2' but generated code is 'col1 * - 22', this
happens for all SQL that has 'hypen' inside the SQL..END SQL block.
Workaround :
If you have any SQL with hyphen then do not put it inside the SQL... END SQL block.
