Macro substitution

[AS]

Hi All,

trying to rebuild avahi, met the following issue:

the file /usr/lib/pkgconfig/avahi-compat-howl is generated with the following content:

Description: Avahi Multicast DNS Responder (HOWL Compatibility)
Version: @HOWL_COMPAT_VERSION@
Libs: -L${libdir} -lhowl
Cflags: -D_REENTRANT -I${includedir}

the  file configure.ac contain the following macro:

AC_SUBST(HOWL_COMPAT_VERSION, [0.9.8])

it seems the substitution doesn't occur.

Hints ?

Thanks

More info, yes, please.     

Short history: Leiche, and not me, was trying to build avahi packages, he was nearly done when an error happened at time
of rpm building:

I helped him to track down where the error come from, in the end the reason was the pkgconfig file mentioned in the original post, containing the illegal char '@'.

There is a similar pkgconfig file where the substitution actually take place, as far as I can understand they are processed the same way. probably not!

I have no idea where to look at ...

$ cat avahi-compat-howl.pc.in
prefix=@prefix@
exec_prefix=${prefix}
libdir=@libdir@
includedir=${prefix}/include/avahi-compat-howl/

Name: avahi-compat-howl
Description: Avahi Multicast DNS Responder (HOWL Compatibility)
Version: @HOWL_COMPAT_VERSION@
Libs: -L${libdir} -lhowl
Cflags: -D_REENTRANT -I${includedir}

$ cat avahi-compat-libdns_sd.pc.in
prefix=@prefix@
exec_prefix=${prefix}
libdir=@libdir@
includedir=${prefix}/include/avahi-compat-libdns_sd/

Name: avahi-compat-libdns_sd
Description: Avahi Multicast DNS Responder (libdns_sd Compatibility)
Version: @PACKAGE_VERSION@
Libs: -L${libdir} -ldns_sd
Cflags: -D_REENTRANT -I${includedir}

after processing the results are:

correct:

$ cat avahi-compat-libdns_sd.pc
prefix=/usr
exec_prefix=${prefix}
libdir=/usr/lib
includedir=${prefix}/include/avahi-compat-libdns_sd/

Name: avahi-compat-libdns_sd
Description: Avahi Multicast DNS Responder (libdns_sd Compatibility)
Version: 0.6.28
Libs: -L${libdir} -ldns_sd
Cflags: -D_REENTRANT -I${includedir}

wrong:

$ cat avahi-compat-howl.pc
prefix=/usr
exec_prefix=${prefix}
libdir=/usr/lib
includedir=${prefix}/include/avahi-compat-howl/

Name: avahi-compat-howl

Hmm...... have you contacted avahi devs? Checked their bug reports?

Hmm...... have you contacted avahi devs? Checked their bug reports?     

no action so far,  you think it is a bug in their source package ?

[Neal ManBear]

Could be. Not sure.
