On Ubuntu 8.04
checking for Tcl installation... configure: error: unable to locate Tcl header file tcl.h
configure: error: ../../../ecos/host/libcdl/configure failed for libcdl
configure: error: ../../ecos/host/configure failed for host

there is no such error in Debian

Re: [ECOS] Tcl install problem with current CVS
http://www.mail-archive.com/ecos-discuss@ecos.sourceware.org/msg07684.html
The issue exists for modern Tcl distributions. eCos's configure system
(look at acsupport/acinclude.m4) belives in that a TCL_INC_DIR variable
presents in tclConfig.sh. But, a new one: TCL_INCLUDE_SPEC had been
entered in modern tclConfig.sh and nowadays it replaces old variable.
So, try to build ecosconfig as
TCL_INC_DIR=/usr/include/tcl8.4 ../host/configure --with-tcl-version=8.4
or add TCL_INC_DIR variable in your site's tclConfig.sh.

Debian+VBox
I installed a Debian 4.0 r0 i3 on VirtualBox, and also the share folder support, and trying to access the shared folder on my Ubuntu /home, but some error occurred. I was root in Debian, but I was like normal user on the shared folder. Even if I I can create file, I failed whenever I try to checkout the eCos source with cvs
# cvs -z3 -d :pserver:anoncvs@ecos.sourceware.org/cvs/ecos co -P ecos ecos-host;
cvs [checkout aborted]: cannot open CVS/Entries.Log: Invalid argument
And ls -al ecos/CVS:
# ls ecos/CVS -al

Even if I checkout code from host, I failed at configuration:

I tried again in a samba shared folder.
  • checkout eCos: No error occurred, just slooooooooow....
  • eCos configuration can be ran successfully. Neither the cross-compiler identification error has occurred.
I already stop trying to build eCos on virtual machine, because I finally fixed the building problem on Ubuntu. Refer to the above steps.
