Hi,
I encountered this problem just before the 2.2.0 release. Then it went
away for a while and came back at the beginning of this week. Here is what
is happening (I am on Win2000 machine with all the necessary tools
installed).
I compile R-devel and R-patched trees every couple of days and install them
in separate directories. Everything seems to work fine for R-patched.
Compilation of R-devel also goes without a problem, but when I try to use
help with the chmhelp=TRUE I get two errors:
1. A separate error windows pops up saying: "The procedure entry point
[EMAIL PROTECTED] could not be located in the dynamic link library hhctrl.ocx"
2. I get the following on the R console
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
'C:/local/R/rw230/bin/Rchtml.dll':
LoadLibrary failure: The specified procedure could not be found.
I tried to track down the problem but I do not know much about CHTML. Here
is what I discovered:
1. The problem is with the Rchtml.dll (as 2 above suggests). If I simply
replace the Rchtml.dll in the bin directory of version 2.3 with Rchtml.dll
from version 2.2 everything works fine!!
2. Rchtml.dll is being built in the .../R-devel/src/gnuwin32/help folder.
The contents of this folder is:
Makefile libhhctrl.a Rchtml.c hhctrl.def Rchtml.o
MkChmDll logo.bmp Rchm.css Rchtml.dll* R.stp
This is identical to the corresponding help folder in R-patched.
3. All files in the help folders in both versions are identical (under
diff) except: libhhctrl.a and Rchtml.dll
4. Doing ar -t libhhctrl.a produces:
dclact.o
dclach.o
dclacs00000.o
in R-dvel but
dquxbt.o
dquxbh.o
dquxbs00000.o
in R-patched.
5. The make process output for building libhhctrl.a and Rchtml.dll is
identical:
...
echo EXPORTS > hhctrl.def
echo [EMAIL PROTECTED] >> hhctrl.def
dlltool --as as -k --dllname hhctrl.ocx --def hhctrl.def
--output-lib libhhctrl.a
gcc -I "C:/Program Files/HTML Help Workshop/include" -c Rchtml.c -o
Rchtml.o
gcc --shared -s -o Rchtml.dll Rchtml.def Rchtml.o -L. -lhhctrl
cp Rchtml.dll ../../../bin/Rchtml.dll
...
I am not sure if this is a problem with my particular setup (version of
hhctrl.ocx perhaps, which BTW is 5.2.3790.309) or a bug in R-devel. Again,
I do not understand the CHTML building process at all, so it is hard for me
to figure out what is going on.
Any help will be appreciated,
Andy
