Comment(by jdemeyer):
Here is a first interesting data point:
Let `tgetent_test.c` be following file:
{{{
#include <termcap.h>
#include <stdlib.h>
int main(int argc, char** argv)
{
char* buf = malloc(100000);
tgetent(buf, "dumb");
}
}}}
Compiling this with
{{{
$ gcc -ltermcap tgetent_test.c -o tgetent_test
}}}
and running it works flawlessly.
However, the same gcc command with the Sage environment variables gives
{{{
$ ( source local/bin/sage-env; gcc -ltermcap tgetent_test.c -o
tgetent_test )
/tmp/ccwDi3Oi.o: In function `main':
tgetent_test.c:(.text+0x27): undefined reference to `tgetent'
collect2: ld returned 1 exit status
}}}
With gcc-4.5.1 (which I happen to have installed in my own $HOME
directory), the compilation works fine again.
