Dev snapshots not built correctly through bootstrap compiler

[iraikov]

The silex egg compiles fine with Chicken 4.6.5, but upon attempting to use it, the following error occurs:

(use silex)
csi: symbol lookup error: /Users/ivan/bin/chicken/lib/chicken/6/silex.so: undefined symbol: C_srfi_2d13_toplevel

silex works with Chicken 4.6.0, so I am guessing this is an issue with the compiler.

This is a known problem if you've built Chicken using an older Chicken; the toplevel C function naming convention has changed, and the new chicken is expecting the function in the new convention, but you've compiled srfi-13 with the old chicken, which generated it using the old convention.

You can either build your Chicken one more time using the *new* Chicken, or use the bootstrap process described in the README.

Ok, does this mean that the development snapshot script needs to be changed so that it bootstraps the build properly?

[sjamaan]

I believe it already does this properly. How did you build your Chicken, and your eggs?

[iraikov]

I thought so too. I simply downloaded the development snapshot tarball from the website, and built it with
`make PLATFORM=linux PREFIX=$HOME/bin/chicken'.

Then $HOME/bin/chicken/bin/chicken-install silex, as usual.

I just double checked to make sure I don't have some old Chicken lying around, but I can indeed confirm that I have removed all old copies of Chicken prior to the steps above.

[sjamaan]

hm, that sounds serious. I'll ask Mario to have a look at this.

Hi,

Unfortunately I cannot reproduce the problem here.

Here's what I did:

• downloaded http://code.call-cc.org/dev-snapshots/2011/02/09/chicken-4.6.5.tar.gz
• built it with make PLATFORM=linux PREFIX=/home/mario/chicken-4.6.5 install (no csi, chicken, csc nor chicken-install in PATH; no libchicken.* in /usr/lib nor /usr/local/lib).
• installed silex using /home/mario/chicken-4.6.5/bin/chicken-install silex
• tried it with (use silex):

$ /home/mario/chicken-4.6.5/bin/csi -n

No error.

Are those steps correct?

Can anybody else reproduce the problem?

Regarding to the dev-snapshots tarballs, the script which generates the tarballs (release/dev-snapshot.sh, from the chicken-infrastructure repo) performs the bootstrap step and generates the C files using the compiler generated by the bootstrap process. Here's the relevant snippet from the script:

### generate the source snapshot
cd $tmpdir/chicken-core
touch *.scm
make PLATFORM=linux CHICKEN=$chicken boot-chicken
touch *.scm
make PLATFORM=linux CHICKEN=./chicken-boot spotless all
$csi -s scripts/makedist.scm PLATFORM=linux CHICKEN=./chicken-boot

$chicken and $csi are 4.6.0rc1.

Here's the ldd output for silex.so:

$ ldd /home/mario/chicken-4.6.5/lib/chicken/6/silex.so

The steps are correct, thanks for trying to reproduce this. I will try it myself again tonight, maybe somehow I clobbered or regenerated the tarball improperly.

The 4.6.7 snapshot works for me.
