Please keep the pre-existing default, i.e. people building pahole all these years expect the shared library to be produced, if after this change that isn't the case, some confusion will ensue. Now if you could provide numbers for, say, 'pahole -J' liked statically, that would be great and would help understand what decision to make. - Arnaldo > Kindly confirm. > -Deepak > > > - Arnaldo > > > >> Signed-off-by: Deepak Kumar Mishra <deepakkumar.mishra@xxxxxxx> > >> --- > >> README | 13 +++++++++++-- > >> 1 file changed, 11 insertions(+), 2 deletions(-) > >> > >> diff --git a/README b/README > >> index 576cd42..40ca984 100644 > >> --- a/README > >> +++ b/README > >> @@ -6,8 +6,17 @@ Build instructions: > >> 4. cmake -D__LIB=lib .. > >> 5. make install > >> > >> -Default is to install to /usr/local, use -DCMAKE_INSTALL_PREFIX= > >> -when invoking cmake to specify another install location. > >> +cmake Options: > >> + -DBUILD_SHARED_LIBS > >> + By default STATIC libraries are created and applications are linked to it. > >> + use -DBUILD_SHARED_LIBS=ON while invoking cmake to create SHARED libraries > >> + and link applications to it. > >> + > >> + Ex. cmake -D__LIB=lib -DBUILD_SHARED_LIBS=ON .. > >> + > >> + -DCMAKE_INSTALL_PREFIX > >> + Default is to install to /usr/local, use -DCMAKE_INSTALL_PREFIX= > >> + when invoking cmake to specify another install location. > >> > >> Known to work scenarios: > >> > >> -- > >> 2.17.1 > >> > > -- - Arnaldo
