z/TPF Program Management - IBM

Set up access to the IBM2047 code page
Using EBCDIC code pages
If you enter the tpf-gcc or tpf-g++ options from the command line to compile C or
C++ segments (such as APACHE HTTPD), you must access the IBM2047 code
page for support of the line feed X'15' value, which is used with the 3215 consoles.
To do this, take one of the following actions:
v Linux administrator action
Request that the GNU/Linux system administrator add the following lines in the
/etc/profile file below the TPF_ROOT= statement where the ${TPF_ROOT}
variable expands to the file system path and the z/TPF source code is always
located:
GCONV_PATH=${TPF_ROOT}/linux/gconv:${GCONV_PATH}
Export GCONV_PATH
v User action
Change your $HOME/.bash_profile file.
If the the GCONV_PATH extension is not specified correctly, the tpf-gcc compiler
option will not complete successfully when -fexec-charset=IBM2047 is run on the
command line, and an error message will result. The following example shows the
kind of error message that can result:
cc1: conversion from cpv to IBM2047 not supported by iconv
Note: Setting up access to the IBM2047 code page is not needed for the
Systems/C and Systems/C++ compilers.
EBCDIC code pages, other than IBM2047, that are used exclusively by the z/TPF
system support the line feed X'15' value. The line feed X'15' value is used with
3215 consoles. These code pages might have been modified to properly match
ASCII-based character encoding, which are used as input character sets. If you
enter the tpf-gcc option from the command line to compile C or C++ segments,
you must set up access to these code pages. If you use the Systems/C and
Systems/C++ compilers, contact the provider for more information about EBCDIC
code page support.
If this setup is not necessary for your development environment, you must specify
one of these code pages as the execution time coded character set instead of the
default value of IBM2047. For example, to use the TPF939 code page, which is a
modified version of the IBM939 code page, specify CFLAGS_USER :=
-fexec-charset=TPF939 or CXXFLAGS_USER := -fexec-charset=TPF939 in your
maketpf.cfg file.
