problems with function system

[Christian Christmann]

Hi,

I have some problems with invoking a shell script out of a c++ program.
The shell script is setting paths with "export PATH=/home/test/gcc/" .

When within my program I use
"string sysCall = "source " + locationOfScrtip;"
[locationOfString is a string containing the location of the script] and
"system( sysCall.c_str() );"

the paths are not set. When I run the script in bash with
"source pathToScrtip" the paths are set correctly .
Any ideas how to solve that problem?

Thanks
Chris

The usual way to use the environment in the operating systems is: each
process has his own environment, when creating a process his environment is
created by copying from the parent, when the child finishes his environment
is destoyed.

Your script sets the environment of the child process that runs int, it does
not touch the environment of the process that is running your program.

Or in a shorter way: you can't do that.
