Hi,


 I am trying to build the seq 2.1.21 and 2.2.6 for linux-ppc64 target

by cross-compiling. And I've got the following error:



```

/opt/fsl-qoriq/current/sysroots/x86_64-fslsdk-linux/usr/bin/powerpc64-fsl-linux/powerpc64-fsl-linux-gcc

                 from ../pv.c:5:

```


Got the hint from EPICS_BASE/CONFIG, I changed seq/configure/CONFIG as

follows:


$ git diff configure/CONFIG

diff --git a/configure/CONFIG b/configure/CONFIG
index 3861c7e..cd9f838 100644
--- a/configure/CONFIG

-  -include $(TOP)/configure/O.$(T_A)/CONFIG_APP_INCLUDE
+  ifneq ($(CONFIG),$(TOP)/configure)
+    -include $(CONFIG)/CONFIG_APP_INCLUDE
+  endif
 endif

The cross compilation works again.


```

```


It looks like somehow OS_CLASS is missing. Can I get some more insights

about them?



The weird CONFIG_SITE.Common.linux-ppc64e6500 is as follows:

```
include $(CONFIG)/os/CONFIG.Common.linux-ppc64

TOOLCHAIN_VER=current
TOOLCHAIN=fsl
TOOLCHAIN_SUFFIX=-qoriq

GNU_TARGET=powerpc64-$(TOOLCHAIN)-linux
SYSROOTS=/opt/$(TOOLCHAIN)$(TOOLCHAIN_SUFFIX)/$(TOOLCHAIN_VER)/sysroots
SDKTARGETSYSROOT=$(SYSROOTS)/ppc64e6500-$(TOOLCHAIN)-linux

CROSS_INCLUDES =

FSL_CFLAG = --sysroot=$(SDKTARGETSYSROOT) -mhard-float -mcpu=e6500

#ARCH_DEP_CPPFLAGS += $(FSL_CFLAG)

ARCH_DEP_CFLAGS   += $(FSL_CFLAG)
ARCH_DEP_CXXFLAGS += $(FSL_CFLAG)
ARCH_DEP_LDFLAGS  += --sysroot=$(SDKTARGETSYSROOT)


ARCH_DEP_CFLAGS   += -pipe -feliminate-unused-debug-types
ARCH_DEP_CXXFLAGS += -pipe -feliminate-unused-debug-types
ARCH_DEP_LDFLAGS  += -Wl,-O1
ARCH_DEP_LDFLAGS  += -Wl,--hash-style=gnu
ARCH_DEP_LDFLAGS  += -Wl,--as-needed

OECORE_NATIVE=x86_64-$(TOOLCHAIN)sdk-linux
GNU_DIR=$(SYSROOTS)/$(OECORE_NATIVE)/usr
GNU_BIN=$(GNU_DIR)/bin/$(GNU_TARGET)
GNU_TARGET_LIB_DIR=$(GNU_DIR)/lib
```

Best,
Han
