Re: [Ltib] Problem with building libcap

[Pauli, David, MU]

Hey,

 

I commented 2 lines in cap_flag.c:

 

From (line 24)

# [...]

# if (raised && good_cap_t(cap_d) && value >= 0 && value < __CAP_BITS

#     && set >= 0 && set < NUMBER_OF_CAP_SETS) {

# [...]

To

# [...]

# if (raised && good_cap_t(cap_d) && value >= 0 //&& value < __CAP_BITS

#     && set >= 0 && set < NUMBER_OF_CAP_SETS) {

# [...]

 

And (line 48)

# [...]

# if (good_cap_t(cap_d) && no_values > 0 && no_values <= __CAP_BITS

#     && (set >= 0) && (set < NUMBER_OF_CAP_SETS)

# [...]

To

# [...]

# if (good_cap_t(cap_d) && no_values > 0 //&& no_values <= __CAP_BITS

#     && (set >= 0) && (set < NUMBER_OF_CAP_SETS)

# [...]

 

Now the error with __CAP_BITS disappeared, but another error cames up:

 

# $ ./ltib -m scbuild -p libcap.spec

Hi David,

If that package does not use configure, then you'll need to look at cap_flag.c .  This will be including headers (some indirect) and in one of those it will define __CAP_BITS.  Maybe for the architecture that define is not enabled.  You'll need to dig a little.

Hey Stuart,

 

yes, I uncommented the ./configure-line. But libcap don’t need a ./configure. So there would be an error, that there is no ./configure in folder (which is correct).

 

So, libcap only needs an

# make

# make install

 

So long, David

Hi David,

__CAP_BITS is not define and is probably created and put in a header when configure runs (or is detected elsewhere by configure).

Have you tried with the configure line uncommented, so it looks like this:

%Build

./configure --prefix=%{_prefix} --host=$CFGHOST --build=%{_build}

make

Hey guys,

 

I want to include a new package to LTIB: libcap2. A tarball is made and moved to /opt/freescale/pkgs.

 

The specfile looks like this:

There is no problem with prepate the file. But I can’t build it with
