Hi,

> I have a general question about the g++ compiler available in buildroot version 1161. I have noticed that the compiler does not inline my template functions if I use -O3 compiler option. It only inlines the function if I mark them with the "inline" keyword. Can I give the compiler special options to solve this problem ? For example VC7.1 does inline the functions without the inline keyword.

According to the gcc help options, one of the following look useful:
  -fdefault-inline            Inline member functions by default
  -fimplicit-inline-templates Emit implicit instantiations of inline templates

You can get the list of options by doing:

cd gumstix-buildroot
cd build_arm_nofpu/staging_dir/bin
./arm-linux-gcc -v --help > gcc.opt 2>&1

and then loading up gcc.opt into your editor for searching.

Hi Marco,

You shouldn't say it's a problem, because that's normal with C++
templates. Even though a function template is defined in a header
file, it's not inline by default. Here's a story that tells inlining
is even more complicated:
