[dpdk-users] error while compiling pktgen-dpdk on RHEL/Centos 7.5

[Murali Krishna]

Hi Keith,

Thanks for the pointing to docs and .pc file example. I tried to build lua
package manually using below steps:

Step 1. updated kernel

Step 2. removed existing lua-devel package

Step 3. downloaded lua-5.3.2.tar.gz and made the below changes:
In /usr/local/src/lua-5.3.2/Makefile, changed "TO_LIB= liblua.a" to "TO_LIB=
liblua.a liblua.so"

In /usr/local/src/lua-5.3.2/src/Makefile
Changed "CFLAGS= -O2 -Wall -Wextra -DLUA_COMPAT_5_2 $(SYSCFLAGS)
$(MYCFLAGS)" to " CFLAGS= -O2 -Wall -Wextra -DLUA_COMPAT_5_2 $(SYSCFLAGS)
$(MYCFLAGS) -fPIC"
Added:
LUA_A=  liblua.a
LUA_SO= liblua.so
Changed "ALL_T= $(LUA_A) $(LUA_T) $(LUAC_T)" to "ALL_T= $(LUA_A) $(LUA_T)
$(LUAC_T) $(LUA_SO)"
Added:
$(LUA_T): $(LUA_O) $(LUA_A)
        $(CC) -o $@ $(LDFLAGS) $(LUA_O) $(LUA_A) $(LIBS)
$(LUAC_T): $(LUAC_O) $(LUA_A)
        $(CC) -o $@ $(LDFLAGS) $(LUAC_O) $(LUA_A) $(LIBS)
$(LUA_SO): $(CORE_O) $(LIB_O)
        $(CC) -o $@ -shared $?


Step 4: exported C_INCLUDE_PATH variable
export C_INCLUDE_PATH=/usr/local/src/lua-5.3.2/src

Step 5: manually added below package configuration file.
# cat /usr/lib64/pkgconfig/lua-5.3.pc
V= 5.3
R= 5.3.2
prefix= /usr
exec_prefix=${prefix}
libdir= /usr/lib64
includedir=${prefix}/include

Name: Lua
Description: An Extensible Extension Language
Version: ${R}
Requires:
Libs: -llua-${V} -lm -ldl
Cflags: -I${includedir}/lua-${V}

Step 6: added below configuration file
# cat /usr/lib64/pkgconfig/lua5.3.pc
V=5.3
R=5.3.2

prefix=/usr
INSTALL_BIN=${prefix}/bin
INSTALL_INC=${prefix}/include
INSTALL_LIB=${prefix}/lib
INSTALL_MAN=${prefix}/share/man/man1
INSTALL_LMOD=${prefix}/share/lua/${V}
INSTALL_CMOD=${prefix}/lib/lua/${V}
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: Lua
Description: An Extensible Extension Language
Version: ${R}
Requires:
Libs: -L${libdir} -llua -lm -ldl
Cflags: -I${includedir}


Step 7: Moved to the lua-5.3.2/src directory and ran `make linux`Step
8: copied newly built libraries to lib64 folder
# cp /usr/local/src/lua-5.3.2/src/liblua.so /usr/lib64/liblua-5.3.so
# cp /usr/local/src/lua-5.3.2/src/liblua.a /usr/lib64/liblua-5.3.a

Now when I try to build latest pktgen-dpdk-3.5.9 or pktgen-dpdk from dev
branch, I get the below error.

Also just updating to the latest Pktgen 3.5.9 will have the updated docs and
.pc file example.
