hugs makefiles and Debian
by Isaac Jones 13 Feb '03

13 Feb '03

Greetings, I'm working on updating Hugs for the Debian GNU/Linux system, and have run into the following problem. With Debian, a package installs its binaries into a temporary directory (known as DESTDIR in Debian Makefiles) and then builds an archive. When the package is installed, it unpacks that archive into the real directory structure. Now I've altered parts of the hugs makefiles to use DESTDIR, so that they install into the correct subdirectories for later packing (and I've attached a patch for that), but I run into the following problem: the program ffihugs is expecting to use the prelude already installed on the system. That is fine when installing from upstream, but since Debian uses this temporary directory, the new Prelude is not installed at this point in the installation process, and so ffihugs dies like this: ---------- /bin/cp ../include/GreenCard.h /home/ijones/usr/src/hugs/hugs98-Nov2002/debian/tmp/hugs/usr/share/hugs98/include /bin/cp HsFFI.h /home/ijones/usr/src/hugs/hugs98-Nov2002/debian/tmp/hugs/usr/share/hugs98/include ./ffihugs -N +G -W +L"../lib/exts/Storable_aux.c" HugsStorable runhugs: Error occurred Reading file "/usr/share/hugs98/lib/Prelude.hs": ERROR "/usr/share/hugs98/lib/Prelude.hs" - Prelude does not define standard type "Int8" make[1]: *** [install_libexts_ffi] Error 1 make[1]: Leaving directory `/home/ijones/usr/src/hugs/hugs98-Nov2002/src' make: *** [debian/binary-arch.stamp] Error 2 debuild: fatal error at line 456: dpkg-buildpackage failed! ---------- Is there a way you or I can alter the build system so ffihugs looks at the right place at the right time? (It looks at $DESTDIR during installation and in the correct place afterward). peace, isaac

Nov2002 Hugs doesn't build properly on Solaris
by Brian Rogoff 12 Feb '03

Hi, Looks like a Makefile problem. If you don't have time or a Solaris system, I'll look at this when I have time. FYI, The last release built fine on this system.

fund transfer
by william ume 12 Feb '03

12 Feb '03

Dear Sir, My name is William Ume, Presently,I am working in an African country. I got your contact via the internet and felt you may be willing to pursue this with me. This proposal may sound strange to you or probably you may even think it is a joke,because of lots of funny mails circulating over the internet .Well if you do,I really understand,but honestly my freind,I am really handicaped,because this is the only means available to me to cominicate to you. Honestly ,I think you should give me a trial,I need your assistance and the deal is good. The deal involves the transfer of $45million,safely intoyour account, and for this you are to receive 20% of the fund. If you are intereted in pursuing this further please contact me via e-mail so that I can furnish you with the relevant detail about the origin of the fund and the modalities for the deal. Please send your response to my e-mail address. William.

hello, i run into the following problem: class C t where elem :: t -- default_elem = 3 -- when default_elem is not used -- INTERNAL ERROR: pmcTerm -- instance C Int where -- elem = default_elem -- when default_elem is used -- INTERNAL ERROR: typeAp1 -- when default_elem is not defined (at command prompt) -- :i default_elem -- default_elem :: <unknown type> it looks like hugs introduces new (valid) names into the program. would it be possible to hide this from the user? thanks iavor -- ================================================== | Iavor S.

bug (?) in type checking of record update
by Johannes Waldmann 04 Feb '03

04 Feb '03

wanna see a large Int in hugs? I mean Int, not Integer. the program below gives this nice result: Main> contents bug 1000000000000000000000000000000 :: Int data Container a = Container { contents :: a , info :: String } bug :: Container Int bug = let xs = 10^30 a = Container { contents = xs , info = "foo" } in a { info = "bar" } it does so even if i write xs = 10^30 :: Integer I checked with hugs-november-2002. With ghc-5.04.2, without the type sig, ghci converts the numeric expression to an Int (silently overflowing); and with the type sig, it rejects the program. best regards, -- -- Johannes Waldmann ---- http://www.informatik.uni-leipzig.de/~joe/ -- -- joe(a)informatik.uni-leipzig.de -- phone/fax (+49) 341 9732 204/207 --
