Building on Cygwin

Building on Cygwin

[thean kiat sew]

Hi, 

I am currently building gcc-3.4.3 using binutils-2.15 on cygwin,
however I encounter this problem, may I know what is the cause?

my configure script output:

Hi Kiat,

>...what is the cause?

I'm not sure if this is the cause of your problem, but it is a problem as far as I know:  you cannot configure & make GCC in the directory of the source, nor in any subdirectory thereof.

Delete your tainted GCC source directory.

Untar your GCC source directory fresh.

Create a peer directory to your GCC source directory.

Inside that peer directory, run the configure process (e.g., ../gcc-3.4.3-source/configure --enable-languages=c,c++ --prefix=/home/newshell/sh1), and then make.

NOTE:  I've had better luck referencing the configure script with a fully specified absolute path, but it appears that most people use a relative path.

HTH,
