Bug #: 50507
Summary: Huge amount of memory used while building GCC4
Classification: Unclassified
Product: gcc
Version: 4.5.3
Status: UNCONFIRMED
Severity: critical
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: fzvq...@v.mintemail.com
when compiling GCC 4.5.3 core (C only), at some point there's a memory
requirement of more than 1 GB RAM.
this happens during the link stage of some object files.
after i set my virtual machine to have 1.2 GB RAM, it worked.
this is a major showstopper, you can only build GCC on restricted platforms
such as an ARM netbook by using swap-memory, which makes the build much slower
as it already is. Additionally this swap memory is usually on flash memory
device on such a system, decreasing its lifetime.
for comparison, GCC 3.4.6 builds well on a virtual machine with just 128 MB
RAM.
