[[bc10/rowboat]] - Contents #contents * Summary [#c22b8cdb] > The previous section has argued what are the requirements for the build process of rowboat-eclair-dsp. It has showed~ how to obtained the mandatory files and explained why the kernel update is required. This section introduces the DSP~ stack and explains how to integrate the DSP stack with rowboat-eclair-dsp.~ * SGX and DSP integration, the DSP stack [#j02d2aa9] **Build [#sed7078f] > Execute the command below, and build the Android kernel, which is integrated with DSP and the userland.~ $ make TARGET_PRODUCT=beagleboard BUILD_WITH_GST=true dvsdk ***Fixing build errors [#h16eb971] > Since the kernel version is updated to 2.6.32, some errors occur as DSP stack is integrated. The locations of errors,~ error message and how to fix these errors are discussed. To use diff -u command, the differences between the original~ and the fixed code are compared. However, this section does not provide the farther explanations of how and why these~ errors happen. ~ > 1. external/ti-dsp/dvsdk_3_00_02_44/dsplink_1_61_03/packages/dsplink/gpp/src/arch/OMAP3530/shmem/Linux/omap3530_phy_shmem.c > ~/rowboat-eclair-dsp/external/ti-dsp/dvsdk_3_00_02_44/dsplink_1_61_03/packages/dsplink/gpp/src/../../gpp/src/arch/OMAP3530/shmem/Linux/omap3530_phy_shmem.c:131: error: implicit declaration of function 'IO_ADDRESS' > $ diff -u omap3530_phy_shmem.c.orig omap3530_phy_shmem.c --- omap3530_phy_shmem.c.orig 2010-06-29 20:53:20.341371121 +0900 +++ omap3530_phy_shmem.c 2010-07-05 14:19:04.614552881 +0900 @@ -128,12 +128,12 @@ halObject = (OMAP3530_HalObj *) halObj ;
