Ulrik,

 

That is not happening for me with R3.13.10 on Windows.  Here is the output I get:

 

cl /nologo /EHsc /GR -c                /D_CRT_SECURE_NO_DEPRECATE /D_CRT_NONSTDC_NO_DEPRECATE /D__STDC__=0   /RTCsu /Zi    /W3 /w44355     -

DEPICS_BASE=h:/epics/base-3.14.10    /MTd -DEPICS_DLL_NO   -I. -I..\\O.Common -I. -I.. -I..\\..\\..\\include\\os\\WIN32 -I..\\..\\..\\include        /Tp ..\\softMain.cpp

softMain.cpp

 

Note that the –D for EPICS_BASE has forward slashes.

 

I am running Visual Studio 2005, Cygwin perl (v5.10.0).  I believe the version of make is an old version from Cygwin before they broke it.

Subject: Escaped strings from fullPathName.pl

 

Hello,

 

In a recent attempt to build base R3.14.10 on Windows I have come across

a build problem in src\softIoc\. The Makefile uses fullPathName.pl to

create an EPICS_BASE variable which is the full path to the base

installation. This is passed to the build of the softMain.cpp with the

-D flag and used in the code to create a C string.

 

Unfortunately fullPathName.pl creates a string with backslashes in it

(when expanding the relative path ../../..). The compiler falls over

when it get to compile this string with backslashes (see build output

below).

 

Strangely enough I have not come across this problem before when I have

build base R3.14.10 under Windows - but I'm now using a new PC with a

fresh installation of the build tools (Same versions as on my old PC

though: Visual Studio .NET 2003, MinGW 5.1.4 for make and perl

(ActiveState) 5.10.0.1003)

 

When I fun fullPathName.pl manually it always seems to produce paths

will backslashes on my PC.

 

I suppose a fix can be done either by adding a flag to fullPathName.pl

to force creation of paths with forward slashes - or alternatively force

the src/softIoc/Makefile to always substitute backward with forward

slashes in the string contained in the EPICS_BASE (local) variable(???)

 

Here is the output of the build of src/softIoc/softMain.cpp:

 

cl /nologo /EHsc /GR -c                /D_CRT_SECURE_NO_DEPRECATE

/D_CRT_NONSTDC_NO_DEPRECATE /D__STDC__=0   /Ox /GL   /W3 /w44355

Has anyone by any chance come across the same problem?

 

Cheers,

Ulrik
