Hi, As from my previous mail to haskell-cafe I'm trying to get started working with a few haskell tools. I'm now trying to get hat to build, but hitting a problem while compiling. The error I get is: Hat/Hat.hs:265: Couldn't match `IOError' against `GHC.IOBase.Exception' Expected type: GHC.IOBase.Exception -> GHC.IOBase.IO (R a) Inferred type: IOError -> GHC.IOBase.IO a1 In the second argument of `catch', namely `exceptionHandler' In a 'do' expression: catch (toIO toId mkRoot (forceExp gmain)) exceptionHandler Hat/Hat.hs:274: Couldn't match `GHC.IOBase.Exception' against `IOError' Expected type: GHC.IOBase.Exception Inferred type: IOError In the first argument of `ioErrors', namely `exception' In the scrutinee of a case expression: ioErrors exception make[1]: *** [/Users/tatd100/Desktop/project/hat-2.02/targets/powerpc-Darwin6/obj/ hatlib/ghc/Hat/Hat.o] Error 1 make: *** [targets/powerpc-Darwin6/hat-lib-ghc] Error 2 during: ghc -I/Users/tatd100/Desktop/project/hat-2.02/include '-#include "hat-c.h"' -cpp -c -o /Users/tatd100/Desktop/project/hat-2.02/targets/powerpc-Darwin6/obj/ hatlib/ghc/Hat/Hat.o Hat/Hat.hs Any help again is much appreciated.

Hat on Cygwin
by Andy Fugard 19 Jun '03

19 Jun '03

Hello folks, Currently having fun trying to install Hat on Cygwin. So far I have got hmake and glib built okay. However on trying to do a "make" on hat, I get the result attached at the bottom. The problem /seems/ to be with glib. Here's what works after doing a "make install" anyway: > $ hmake -hat sort.hs > hat-trans sort.hs > Wrote Hat/sort.hs > ghc -c -package hat -o Hat/sort.o Hat/sort.hs > c:\ghc\ghc-5.04.3\bin\ghc.exe: unknown package name: hat (So hmake and hat-trans at least seem to be okay.) I'm not sure what other information would be useful, but for starters, some version info: glib-1.2.10 hat-2.02 hmake-3.07 The only other thing that could be useful is the following message on doing a "make install" for glib: > Libraries have been installed in: > /usr/local/lib > > If you ever happen to want to link against installed libraries > in a given directory, LIBDIR, you must either use libtool, and > specify the full pathname of the library, or use `-LLIBDIR' > flag during linking and do at least one of the following: > - add LIBDIR to the `PATH' environment variable > during execution > - add LIBDIR to the `LD_RUN_PATH' environment variable > during linking > - use the `-Wl,--rpath -Wl,LIBDIR' linker flag > > See any operating system documentation about shared libraries for > more information, such as the ld(1) and ld.so(8) manual pages. Any help would be very much appreciated!

Control.Monad.State
by Isaac Jones 21 May '03

21 May '03

Thanks, Olaf for your last reply. That seems to have helped. However, I still cannot debug my program because the interface files for Control.Monad.State are not there. Is there a good way to generate these files, or are they distributed seperately? The error I get is as follows: hat-trans TestData.hs Fail: does not exist Action: openFile Reason: No such file or directory File: /usr/local/include/hat/Control/Monad/State.hx peace, isaac

06 May '03

FROM:MRS. M SESE-SEKO DEAR FRIEND. I AM MRS. MARIAM SESE-SEKO WIDOW OF LATE PRESIDENT MOBUTU SESE-SEKO OF ZAIRE? NOW KNOWN AS DEMOCRATIC REPUBLIC OF CONGO (DRC).I RECEIVED YOUR COMPANY PROFILE FROM THE CHAMBERS OF COMMERCE IN MOROCCO. I AM MOVED TO WRITE YOU THIS LETTER, THIS WAS IN CONFIDENCE CONSIDERING MY PRESENT CIRCUMSTANCE AND SITUATION. I ESCAPED ALONG WITH MY HUSBAND AND TWO OF OUR SONS EMMANUEL AND MUKOKO OUT OF DEMOCRATIC REPUBLIC OF CONGO (DRC) TO ABIDJAN, COTE D'IVOIRE WHERE MY FAMILYAND I SETTLED, WHILE WE LATER MOVED TO SETTLED IN MOROCCO WHERE MY HUSBAND LATER DIED OF CANCER DISEASE. HOWEVER DUE TO THIS SITUATION WE DECIDED TO CHANGE MOST OF MY HUSBAND'S BILLIONS OF DOLLARS DEPOSITED IN SWISS BANK AND OTHER COUNTRIES INTO OTHER FORMS OF MONEY CODED FOR SAFE PURPOSE BECAUSE THE NEW HEAD OF STATE OF (DRC) MR LAURENT KABILA HAS MADE ARRANGEMENT WITH THE SWISS GOVERNMENT AND OTHER EUROPEAN COUNTRIES TO FREEZE ALL MY LATE HUSBAND'S TREASURES DEPOSITED IN SOME EUROPEAN COUNTRIES. HENCE MY CHILDREN AND I DECIDED LAYING LOW IN AFRICA TO STUDY THE SITUATION TILL WHEN THINGS GETS BETTER, LIKE NOW THAT PRESIDENT KABILA IS DEAD AND THE SON TAKING OVER(JOSEPH KABILA). ONE OF MY LATE HUSBAND'S CHATEAUX IN SOUTHERN FRANCE WAS CONFISCATED BY THE FRENCH GOVERNMENT, AND AS SUCH I HAD TO CHANGE MY IDENTITY SO THAT MY INVESTMENT WILL NOT BE TRACED AND CONFISCATED. I HAVE DEPOSITED THE SUM OF ONE HUNDRED MILLION UNITED STATEDOLLARS(US$I00,000,000,00.) WITH A SECURITY COMPANY , FOR SAFEKEEPING. THE FUNDS ARE SECURITY CODED TO PREVENT THEM FROM KNOWING THECONTENT. WHAT I WANT YOU TO DO IS TO INDICATE YOUR INTEREST THAT YOU WILL ASSIST US BY RECEIVING THE MONEY ON OUR BEHALF. ACKNOWLEDGE THIS MESSAGE, SO THAT I CAN INTRODUCE YOU TO MY SON (EMMANUEL) WHO HAS THE OUT MODALITIES FOR THE CLAIM OF THE SAID FUNDS. I WANT YOU TO ASSIST IN INVESTING THIS MONEY, BUT I WILL NOTWANT MY IDENTITY REVEALED. I WILL ALSO WANT TO BUY PROPERTIES AND STOCK IN MULTI-NATIONAL COMPANIES AND TO ENGAGE IN OTHER SAFE AND NON-SPECULATIVE INVESTMENTS. MAY I AT THIS POINT EMPHASISE THE HIGH LEVEL OF CONFIDENTIALITY, WHICH THIS BUSINESS DEMANDS, AND HOPE YOU WILL NOT BETRAY THE TRUST AND CONFIDENCE, WHICH I REPOSE IN YOU.IN CONCLUSION, IF YOU WANT TO ASSIST US , MY SON SHALL PUT YOU IN THE PICTURE OF THE BUSINESS, TELL YOU WHERE THE FUNDS ARE CURRENTLY BEING MAINTAINED AND ALSO DISCUSS OTHER MODALITIES INCLUDING RENUMERATIONS FOR YOUR SERVICES. FOR THIS REASON KINDLY FURNISH US YOUR CONTACT INFORMATION, THAT IS YOUR PERSONAL TELEPHONE AND FAX NUMBER FOR CONFIDENTIAL PURPOSE AND ACKNOWLEDGE RECEIPT OF THIS MAIL USING THEABOVE EMAIL ADDRESS.BEST REGARDS, MRS M. SESE SEKO
