Haven't managed to get it to find bdw-gc, despite building and installing it..


Due this is other difficulties, I tried building guile 1.8.7 with native cc:


libtool: compile:  cc -DHAVE_CONFIG_H -I.. -I/home/jayk/src/guile-1.8.7 -I.. -ieee -ieee -D_REENTRANT -pthread -I/home/jayk/include -L/home/jayk/lib -c -MD /home/jayk/src/guile-1.8.7/libguile/hashtab.c  -DPIC -o .libs/libguile_la-hashtab.o
cc: Error: /home/jayk/src/guile-1.8.7/libguile/hashtab.c, line 914: The static declaration of "s_scm_hash_fold" is a tentative definition and specifies an incomplete type. (incompstat)

static const char s_scm_hash_for_each[];

bash-4.1$ diff  orig/guile-1.8.7/libguile/hashtab.c guile-1.8.7/libguile/hashtab.c
914c914
< static const char s_scm_hash_fold[];

952c952
< static const char s_scm_hash_for_each[];
---
> static const char s_scm_hash_for_each[sizeof("hash-for-each")];


bash-4.1$ cc -V
Compaq C V6.3-025 on Compaq Tru64 UNIX V5.1 (Rev. 732)
Compiler Driver V6.3-026 (sys) cc Driver


It the compiles ok. I don't hit the isinf error, not surprising, since there's then no -Wmissing-prototypes.

Usually this is a pkg-config problem. Where is bdw-gc.pc ? Where is
pkg-config? What prefix are you installing Guile to?

Thanks for the report. I have fixed this on the 1.8 and development
branches.

-prefix=$HOME
Indeed, duh to me, there is no bdwcgc.pc.
I'm not entirely sure I even built the right package..or built it property.

There is http://hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gc-7.1.tar.gz
First I had gc-latest.tar.gz which is 6.8.
In neither case do I get package config file though.


I'll have to root around later..

Thanks,
  - Jay

Just to be clear, that would be bdw-gc.pc. You would need to add
$HOME/lib/pkgconfig to your $PKG_CONFIG_PATH.

You should have one with 7.0 or later.

Ciao,

[Jay K]

But I also installed pkg-config to -prefix=$HOME. I don't think that's the problem, but something is amiss. I'll have to dig more, later.
I was just improvising/approximating on the file name.

Thanks, more later,
