Hi, I migrated from my old Celeron to a virtual machine (KVM) on AMD64 (but the VM is 32 bit). I checked out the Yhc repo, but cannot even start building because of strange error scons reports: ============================= [dima@dmgdevel yhc]$ scons core=1 prefix=/home2/dima/install/ build scons: Reading SConscript files ... Building version 0.7.0-20070712053136-custom. Checking for architecture... x86 Checking for operating system... linux2 Checking for Subversion binary... "svn" Checking for Subversion version...

Python 2.3 or later must be used to compile Yhc" Looks like that Configure is a pointer to some function passed as a parameter . If I try to get some debug information from scons, I get (only debug=includes gave me something) ============================= [dima@dmgdevel yhc]$ scons --debug=includes core=1 prefix=/home2/dima/install/ build scons: Reading SConscript files ...

This occurred with both most recent scons (0.97) and Python (2.5.1), and after I downgraded to scons 0.96.1 and Python 2.4.4c1 (these worked fine on my old Celeron) I don't believe there are any issues based on the fact that this is VM: I was able to compile ghc 6.6.1 from sources (several hours), and there were no problems (except that gcc 4.2.1 did not work, I used gcc-3.3, but this is a known issue related to gcc itself). The VM runs (output from uname -a) Linux dmgdevel 2.6.22-rc5-ARCH #1 SMP PREEMPT Sun Jun 24 11:12:27 CEST 2007 i686 QEMU Virtual CPU version 0.9.0 AuthenticAMD GNU/Linux libc 2.6 Thanks. -- Dimitry Golubovsky Anywhere on the Web
